ECE’s brand new robots demonstrate their dexterity and Lobo Spirit
ECE Robots do a Latin Dance in MARHES Labs
It's summertime and things have slowed down quite a bit at ECE. Most of our students are enjoying a well-deserved vacation as they prepare for another year of classes in the fall.
Summer school is underway and those students who wish to pursue their academic study are burning the midnight oil under the tutelage of some of UNM’s best professors.
Our 29-year-old building, which suffered extreme flood damage last summer, has risen from the ashes like the legendary phoenix and boasts lots of new carpet, paint, furniture, air handlers, LED lighting, as well as a 10-foot-diameter “Big Ass Fan” which overlooks the atrium like the grand chandelier in the Phantom of the Opera.
Two interns from La Cueva High School can be found hard at work in the basement of ECE in in the MARHES Laboratory, contributing their youthful vigor to the department as they strive to come up with innovative solutions to some of the world’s problems.
15-year-old Akshay Jain is working with Turtlebots (a low-cost personal robot) to design algorithms that allow multiple robots to work together to develop a single 3D-map of an area autonomously.
“I find opportunities like this to be outstanding and a great way to spend my free time. I feel very privileged to be working here,” said Askhay
16-year-old Alex Cuellar is also working with his friend on the same project.
“It’s not every day that a kid my age can work with professional equipment at a major, respected university,” said Alex. “It’s a once-in-a-lifetime opportunity that I will carry with me throughout the rest of my academic and career life.”
In addition to employing young and promising high school students, Dr. Fierro has recently received a BAE Systems (Army Research Laboratory) grant supplement. The project title is “Exploiting Heterogeneity in Wireless Aerial and Ground Robotic Networks.”
When I peeked into the doors of Fierro’s laboratory I couldn’t help but notice the presence of two enormous red robots.
“We just got the robots two weeks ago. There is not much to say about them right now,” said Fierro somewhat impatiently. “My graduate student is just helping to make sure we got what we ordered and nothing was broken. Let’s talk in the fall semester when we have a story to tell.”
The graduate student, with Fierro’s permission, demonstrated the dexterity of ECE’s new robots by programming a performance of Latin Dance which is shown on the YouTube video at the top of this page.
And, if that’s not a story that’s just itching to be told, I don’t know what is.

Members of the UNM Physical Plant pose beside ECE's new "Big Ass" Fan
Physical Plant Helps to Solve Heated Problem
ECE students work hard and the department wants to give them a nice place to learn and study.
Thanks to the work of the UNM physical plant, ECE students will be more comfortable than ever.
"I learned a long time ago that civils only get complaints and never any compliments!" said ECE Chair Jane Lehr, who is eager to acknowledge the phenomenal work done by the physical plant.
Not only has the ECE building been extensively remodeled with new carpeting, new paint, new furniture and a new ventilation system but also a problem that has been plaguing the 30-year-old building has finally been solved.
“The problem we were facing in the winter,” said building manager David Modisette, “was that the temperature at the bottom of the atrium would be 68 degrees and 88 degrees at the top.
“We could turn the heat up at the bottom but it would always rise to the top,” he said.
Modisette recently mentioned this ongoing problem to the UNM physical plant and they suggested the use of a fan.
Anybody who has visited the ECE department knows that the three-story tall atrium is an enormous space so an ordinary fan would not work.
The Physical Plant turned to the Big Ass Fan Company (that’s their real name) based in Lexington, Kentucky and they recommended investing in their Isis Ceiling fan.
With eight blades, each fin measures five feet for an overall diameter of 10 feet. With a sound level of only 35 decibels, the 88 pound fan can be barely heard by the students working far below.
“The fan is attached to the I-beams of the ceiling by two angle iron beams are about an inch wider than recommended and supported by additional safety cables,” said Modisette.
The fan has speed and directional adjustment so that hot air can now be forced to circulate in the winter. Five plastic gratings in the ceiling also help circulate the air.
“It’s perfectly perpendicular and it doesn’t wobble at all,” Modisette said, admiring the work of the physical plant. “This fan should make the atrium lobby much more comfortable for everybody.”

Forever Young: Three Faces of Zhen Peng (High School, College and Now)
Zhen Peng Wins ACES Early Career Award
ECE Prof Zhen Peng was awarded The Early Career Award by the Applied Computational Electromagnetics Society (ACES) at its Conference last March in historic Williamsburg, Virginia. This award honors achievements and contributions in the field of computational electromagnetics by a researcher who is under 35 years old.
Peng was chosen for the Early Career Award because of his outstanding contributions to domain decomposition methods in computational electromagnetics. His research allows engineers to quickly create and analyze “virtual” prototypes and reduces the need to conduct experiments with real prototypes.
“Zhen is one of the top 10 young computational EM folks in the world in terms of promise and visibility,” said ECE Professor Christos Christodoulou. “He has been very consistent in solving more and more complicated problems in our fields.
Computational electromagnetics (CEM) is important for virtual prototyping of engineering products. It can be used to explore new theories and to design new experiments to test these theories. CEM provides a powerful alternative to the techniques of experimental science when measurements are impractical or too expensive. Applications include electromagnetic compatibility, antenna analysis, radar signature prediction, and design of optical materials.
“We were pleased when Zhen Peng agreed to join our faculty because we knew of his potential and he is simply fulfilling our expectations,” said ECE Professor Edl Schamiloglu. “The University of New Mexico has one of the top Applied Electromagnetics programs in the country and we look forward to becoming THE applied electromagnetics program in the country.”
Peng was thrilled when he found out that he won the award.
“As a researcher who is passionate about computational electromagnetics and mathematics, receiving this award is an amazing honor,” said Peng, who is 33. “I am very grateful and fortunate to work with great mentors and collaborators, amazing and supportive colleagues and students in the applied electromagnetic group at UNM. The award is an encouragement and inspiration to continue this research and to drive me towards achieving greater accomplishments.”
Peng joined ECE as an Assistant Professor on August 1, 2013. Prior to joining UNM he was a Senior Research Associate at the ElectroScience Laboratory at the Ohio State University (2009-2013). He Received the Ph.D. degree in 2008 at Chinese Academy of Sciences and his thesis work was awarded first Prize at Beijing Science and Technology Progress in 2010. Peng earned his B.S. in Electrical and Computer Engineering at The University of Science and Technology of China.
Peng is the recipient of 2014 IEEE Antenna and Propagation Sergei A. Schelkunoff Transactions Prize Paper Award, a recipient of 2014 Young Scientist Award of Union Radio-Scientifique Internationale (URSI) General Assembly and Scientific Symposium, 2013 Young Scientist Award of the International Union of Radio Science, Commission B, 2013 Young Scientist Award of International Symposium on Electromagnetic Theory, 2013 Young Scientist Award of Asia-Pacific Radio Science Conference, a candidate for 2012 P. W. King award of IEEE Transactions on Antennas and Propagation, the recipient of the Best Paper Award for 2011 from ElectroScience Lab, The Ohio State Unviersity, and a recipient of Young Science Award from International Symposium on Electromagnetic Theory.

"This current chamber is what a real Anechoic Chamber should be!"
Antenna Chamber Built to Industry Specs at ECE
How do you fit a 1,373 cubic foot Anechoic Chamber in the cramped confines of a basement laboratory at ECE?
That was one of the questions ECE Professor Christos Christodoulou grappled with when he decided to construct a room that could be used to test antennas.
Christodoulou and his team (Research Professors Youssef Tawk and Joseph Costantine; Graduate Students Firas Ayoub, Chris Woehrle and Arjun Gupta and undergraduate Clayton Merritt) decided to build the chamber from the ground up, using many materials readily-available from Home Depot. They could have bought the chamber “off-the-shelf,” from a scientific supply company, but that would have been much more expensive and would not necessarily have been better.
“We designed it to fit our available space,” said Christodoulou. “Doing it ourselves also helped my students learn how to design and build these chambers.”
The students learned a lot. Chris Woehrle, who is working on his PhD dissertation under Christodoulou spoke enthusiastically about the chamber.
“This chamber allows us to accurately measure the radiation patterns of our antennas,” said Woehrle. “Prior to this we had a crude set-up — it was pretty bad. This current chamber is what a real Anechoic Chamber should be.”
The problem with off-the-shelf Anechoic Chambers is that they come in prefabricated sizes. The chamber that Christodoulou and his team built was designed and built for their lab so that they could effectively use the floor space that was available to them.
By customizing their chamber the ECE antennas team was able to create a testing environment that surpassed anything they could have bought on the market. Now that the chamber is built, all of Christodoulou’s students can be trained to use the equipment. They include PhD candidates Xuyuan Pan, Elizabeth Zamudio, Georgios Atmatzakis, Hamide Faraji and Master’s student Katherine Belvin.
“Most chambers are designed specifically for one type of application and they tend to be for radiation measurement,” continued Woehrle. “But this chamber is built so it can be reconfigured to test more than radiation patterns. The magnetic back radar absorbing material allows us to change the chamber into a mode stir chamber.
“The cool thing is: most of the time you need two chambers but by having a reconfigurable chamber makes it like a one-size-fits all scenario.”
Thanks to this newly-built chamber, the ECE antennas group can now make complete and accurate measurements to industry standards.
But it doesn’t end there. The chamber has been such a big hit that others are clamoring for time to use it as well.
“We now have organizations from outside UNM asking us to use our facility for antenna measurements,” said Woehrle.

Anees Abrol, Ramiro Jordan and Eric Hamke: The Power of Three
Jordan Offers MATLAB and LabVIEW Classes
“Three” may be considered a crowd to some people, but not to Dr. Ramiro Jordan.
Jordan has recruited PhD students Anees Abrol and Eric Hamke to assist him in the teaching of two three-credit hour ECE courses in Advanced MATLAB and Advanced LabView, to take place Mondays and Fridays from March 16 to May 9.
Jordan lovingly refers to his assembled trio as “The Three Stooges” but his goal in creating these two courses is anything but comic.
Jordan brings 20 years’ experience of teaching in the University environment to the classroom, as well as his understanding of how a course should be run and evaluated.
Hamke developed training courses for the use of MATLAB at Honeywell and is considered a national expert on the subject. And Anees devised a lab-based course on communication systems at National Instruments in 2014.
“Students are expected to use MATLAB and LabView in their course work and projects,” said Hamke. “One of the questions they will be asked during a job interview or when their resumes are screened is their knowledge of, or their familiarity with, these tools.”
MATLAB has become an industry standard design and analysis tool used by companies like Ford, General Motors, the DoD, the FAA, Sandia National Labs and Los Alamos. They use MATLAB to reduce development costs by creating a virtual environment for testing designs. By using MATLAB these organizations don’t have to employ manpower in a project nor do they have to build experimental designs that may or may not work out.
Similarly, LABView has also become an industry standard for data acquisition and processing in real-time. LABView is used in the manufacturing industry and by SpaceX to monitor the launch of their rockets. It was also instrumental in the discovery of the Higgs-Boson particle at CERN.
“We are hoping that by combining our strengths we can develop a well-balanced course that reflects the needs of the University,” said Hamke.
ECE Professors Sanjay Krishna and Daniel Feezell were featured on two local TV news stations this week.
Krishna and Feezell work in different fields but their research has caught the public's attention because they both hit so close to home: Afterall, what could be more personal than protecting the PIN numbers of our debit cards? And what could be cooler than a novel way of projecting and viewing images we are used to seeing on a flat screen monitor?
In a story aired on KRQE news 13, Krishna, the director of the Center for High Technology, was interviewed about his research into the uses (and abuses) of tiny infrared cameras that are now entering the marketplace. These pocket-sized, $250 devices help airplane pilots land and firefighters see through smoke, but they canalso cause the rest of us a world of pain: Criminals can now figure out the PIN numbers of our debit cards by the sequential heat imprint left behind on an ATM's keyboard.

Feezell's research was featured on KOAT channel 7 news and concerns the development of blue and green lasers. Everybody knows about red lasers but imagine the potential of combining that red laser light with blue and green laser light! The National Science foundation has awarded Feezell a $500,000 grant to discover new ways of improving the usefulness of lasers in ways that are going to knock our socks off!

New Shared Credit Degree Program in ECE: BS/MS in EE or CompE
In line with the new shared credit degree program initiative of the School of Engineering, the Department of Electrical and Computer Engineering will allow students to complete a BS and MS degree in five years. The key idea behind the program is that some courses are allowed to be counted towards both the Bachelors and Masters degrees.
In pursuit of continuous process improvement the ECE Department is investing resources into class scheduling. The ultimate goal is to enable students to navigate the curriculum and to graduate in a minimum period of time by eliminating class conflicts and efficiently utilizing resources. Fall 2015 has been targeted for rolling out a Master Schedule that meets these requirements.
ECE Professor Vince Calhoun recently became the focus of local and national news after co-authoring an 8,000 word paper that appeared in the Nov. 12 edition of the Proceedings of the National Academy of Sciences
Vince Calhoun Scores: PNAS Paper is a Hit!
By Charles Reuben — December 1, 2014
Newspapers and TV reporters often tell us stories about new scientific triumphs: cures for cancer, the launching of spaceships and the development of new energy sources. But rarely does a scientific paper itself become the center of attention.
Despite this, ECE distinguished professor Vince Calhoun recently became the focus of local and national news after co-authoring an 8,000 word paper that appeared in the Nov. 12 edition of the Proceedings of the National Academy of Sciences (PNAS). Calhoun’s paper can be found here
PNAS was created in 1914 and is one of the world’s most-cited and comprehensive multidisciplinary scientific journals. It is a scholarly publication that raises the eyebrows of researchers and scientists but not many others. The paper that Calhoun co-authored was entitled“Long term effects of marijuana use on the brain.”
“This is probably the largest multimodal brain imaging study of marijuana to date,” said Calhoun in a recent interview. “[The paper is] significant in that it shows the changes between cannabis users and controls across multiple types of brain imaging.”
It seems that Calhoun was in the right place at the right time. New Mexicans had just returned from voting in their mid-term elections and were processing the results of a referendum that asked them whether they wanted to decriminalize the use of marijuana.
The results of this November 8th election were decisive. Bernalillo County voted in favor of decriminalization 60 to 40 percent. In Santa Fe, the results were 73 percent to 26 percent in favor of decriminalization.
So it seems there was broad interest in the topic of marijuana in New Mexico and beyond when Calhoun’s paper was finally published by PNAS after months of intense peer review. The results in the study show difference in the brain in marijuana users compared to non-users, which in turn fostered much discussion.
The attention received by Calhoun’s paper was impressive:
On Nov. 10, 2014, two days before the story was released on the internet, ScienceDaily wrote a story that elegantly encapsulated the essence of the paper. It can be found here
On Nov. 11, one day before the paper was officially released on the internet, CNN published a story based on the paper in their health section. Click here to read the story.
And on Nov. 24, The Daily Lobo, the independent newspaper at the University of New Mexico, joined the pack by publishing the following story,
“I myself have a hard time understanding the study . . ." said J.R. Oppenheim, managing editor of The Daily Lobo.
“I can tell you,” Oppenheim continued, “[that] a key component of a newspaper journalists' job is to take difficult information and present it in a way to make it understandable to as many people as possible.”
“A journalist needs to strike that balance between jargon and laymen terminology in order to provide readers with the key information. It's not easy, but it's essential,” said Oppenheim.
Despite the fact that very few laymen actually read Calhoun’s paper, his message appeared to get around the country, if not the planet, thanks to a handful of dedicated journalists who captured the story in Calhoun’s study at a level that most of us can understand.
When Calhoun was asked about the success of the paper, he modestly replied that there was “lots of interest. Much of it is hitting the first author primarily. No paparazzi though, thankfully. I suspect it will fade out like everything does, until the next paper.” The lead author, Francesca M. Filbey designed the study and received the funding. Calhoun was primarily involved in helping set up the scanning and performing the analysis.
And it would appear that there is another paper forthcoming. He said that his group is now “looking at other variables to see if those are related to cannabis use, looking at doing brain scans in the same person before and after use, and studying other data, for example, brain imaging collected from children whose mother smoked pot.”
Vince Calhoun speaks candidly here about the subject matter of a paper that challenged so many members of the media:
STEM students were recently sent on a Scavenger Hunt by the "S-Cubed" group to take "selfies" in front of the iconic UNM landmarks shown above.
UNM STEM Gateway Targets ECE Students
By Charles Reuben — November 1, 2014
It’s not easy being a STEM(Science, Technology, Engineering and Mathematics) student: The coursework is difficult and the students often feel it is a competition, rather than a network of support.
It’s even tougher being a STEM student when he or she comes from one of the 43% of the families in New Mexico who live in poverty. Or, for those who didn’t get a proper education before they entered UNM.
Regardless of a student’s past or current situation, it is difficult to adjust to the demands of college, especially within the STEM fields. They often feel unprepared to meet demands of college life. Fortunately, there is hope for STEM students in all stages of their college careers, even if they are struggling financially or academically: The STEM Gateway Program at UNM.
Dr. Yadéeh E. Sawyer is a program specialist at UNM's STEM Gateway Program and she has made her presence felt at ECE lately, even though she is not part of the School of Engineering.
ECE students, faculty and staff regularly receive personal invitations, slick flyers, and fancy posters from Sawyer. She reaches out and encourages ECE members, ranging from pre-majors through faculty and staff, to attend free workshops, activities, and programs. Working from an austere, cramped cubical in the College Enrichment and Outreach Programs (CEOP) near Career Services, she is part of a team that is making things better for all STEM students.
“We aim to serve all UNM STEM students, but focus especially on Hispanic, low-income, and/or first generation students,” said Sawyer during a recent interview. “STEM Gateway Activities are designed to help new STEM students transition successfully into the academic disciplines. But all students are welcome to participate in all STEM Gateway events and services, regardless of major or economic status.”
Sawyer said that the reason her group targets “Hispanic, low-income, and/or first generation students” is because the data shows that these groups have lower retention rates, especially within the STEM fields. She said that a “first generation student” is one who’s parents have not attended college — they are the first generation in their family line to pursue a college degree.
“Any and all students are welcome, encouraged to join, and will fit in, regardless of their background or current academic focus,” Sawyer said. “A lot of our events are geared towards life skills and applicable to any student.”
Sawyer glowed when she began talking about the activities that bring STEM students together.
“We know that it can be tough for STEM students to build a community, but students are each other's best support system: We want them to be able to connect with each other, as well as faculty and staff mentors. These networks can provide a sense of belonging, mental stimulation, as well as potential job or research opportunities,” she said.
STEM Gateway Activities are designed to help new STEM students transition successfully into the academic disciplines. The activities that would best apply to ECE students would be the AEON (Achievement, Exploration Opportunities & Networking) Workshops, and S3 (Students for STEM Success) Activities.

Additionally, many core STEM classes have Peer Learning Facilitators (PLFs) who are always there for them.
Sawyer can’t help solve every problem that faces a STEM student, but she is eager to point a STEM student in the right direction. They can e-mail her at Yadeeh@unm.edu or you can leave her a message at 277-2257.
“The S-cubed students are shifting to a more student centered group that will have monthly meetings for networking and planning. This is a great way for STEM students to meet and mingle are the various events and workshops that we offer throughout the semester.Her closing remarks, directed at all students even remotely in STEM is “You belong! And remember, you are not alone.”
Although it was a team effort, Cruz got to be the star of the robotic video.
Patricio Cruz Really Wants You to Like Robots
By Charles Reuben — October 15, 2014
If a picture says a thousand words then Patricio Cruz figured that a moving picture could tell ten thousand more.
"Our team's approach, and the experimental results that were presented in this video, were based on a contributed paper entitledStable Formation of Groups of Robots via Synchronization," said Cruz.
IROS is one of the major annual international conferences in the field of robotic research. As second author, he created a three minute video of his team’s work during the multi-robot coordination session. Although it was a team effort, Cruz got to be the star.
This video format was new for me,” said Cruz, who is used to defending his ideas beside static posters. “It gave me the opportunity to efficiently present the main contributions of our research in a short time.”
The attention received by his video exceeded his expectations.
“Indeed,” said Cruz modestly, “my three-minute talk attracted the attention of professors and graduate students who wanted to know more details about our work. For example, I got interviewed about our work by the people of Robohub.”
Robohub is a non-profit online communication platform that connects the robotics community to the general public. With the video he will be able to promote robotic research that is being carried out at UNM.
Cruz works in the Multi-Agent, Robotics, Hybrid, and Embedded Systems (MARHES) Lab under the supervision of Prof. Rafael Fierro. His research focuses on the coordination control of multiple robots that have different dynamics and/or capabilities.
Cruz works in the basement robotics lab at ECE with Luis Valbuena and Rafael Figueroa. He also collaborates with ofProf. Francesco Sorrentino from the ME department. Together, they have developed a decentralized controller for the stable formation of heterogeneous groups of robots to enhance line-of-sight communications between the members of the different groups.
“We tested our approach carrying out several experiments using the aerial and ground robotic platforms available at the MARHES Lab,” said Cruz. “A reliable wireless data transmission is an important factor in this type of robotic networks especially for task coordination.”
What makes Cruz’s recent video unique is that there is a person in it. All the rest of his videos are experiments that contain no people.
So, will Cruz and his colleagues start standing in front of the camera more often?
“We have Robots here!” said Cruz, “ECE has a good robotic platform to carry out experiments. And if we have to get in front of the camera, we will do it!”
The Poster Competition was one of the many highlights of CS/ECE Day
Hossain Wins People's Choice; Judge Speaks Out
By Charles Reuben — October 1, 2014
Winning first or second place isn’t always everything.
ECE Graduate Student Mattaleb Hossain walked away with the People’s Choice Award at the CS/ECE Tech Talent Showcase held September 10: After the ballots of the 100+ attendees were counted, his poster was declared crowd favorite.
Bill Hartman, President and CEO ofIon Linac Systems in Albuquerque, was one of the seven judges presiding over the contest and he had a lot to say about posters, entrepreneurialism, young people and whether the opinion of a panel of judges would guarantee the success of an idea.
“At the end of the day some sort of market mechanism will figure it out, even if the market selects what the judges didn’t happen to pick,” said Hartman. “And I would love to see the University put more fuel on that fire.”
Tech Day was an example of how UNM ignited an inferno. The poster competition, which attracted 20 entrants (four from ECE) was a collaboration between the Computer Science Department and ECE. The competition was fierce, fiery and Hartman was impressed.
“There’s a lot of knocking of younger folks nowadays as not being really invested in learning or making changes in the world. I could see how much pride of ownership and how much work and how many hours went behind each and every one of these posters…and that’s pretty encouraging,” he said.
Posters are one of the ways that engineers talk to each other, especially at conferences and IEEE poster sessions. Posters are a way for them to communicate their ideas with their peers and a way for them to get feedback. A typical poster session looks like an art opening: the young engineer stands before his poster, surrounded by (one hopes) a friendly crowd and fiercely defends his or her ideas.
Posters are especially important to the engineer who is just starting out. Hartman explained that it is much easier for a newcomer to share a poster with their peers but, often posters are only the first step in developing a project.
“There’s a pecking order and invited papers are usually more rigorously evaluated,” said Hartman. “it’s tougher to get (a paper) in: your credentials have to be more established. The poster sessions tend to be less rigorous and therefore, on average, less baked. The ideas are more earlier on and starting to develop, as opposed to something that you might expect to see and go, “Wow, that’s ready to go.”
“But within engineering communities, posters are the way you do it,” continued Hartman. “They are part of the culture. It’s part of the way an engineer communicates officially with other engineers and it’s the first step towards getting published.”
Hartman calls himself 1/3 engineer and 2/3 businessperson and he is exactly the kind of person that ECE graduates are going to have to impress if they want to bring home a paycheck someday.
“Engineers don’t necessarily start with a business problem in mind, they start with a technical problem that they’re trying to solve and then look for where that technology might be applied to solving a kind of a real world business problem.”
Cognitive radios: Next step in the evolution of wireless communications?
Jayaweera to Give Radiobots Keynote at TSSA ’14
By Charles Reuben — September 15, 2014
Your smart phone wants to get to know you. And if Sudharman Jayaweera, an ECE Associate Professor, has any say in the matter, it will get to know you, whether you “like” it or not .
Jayaweera uses the word “radio” when he refers to his research. By that he means any wireless mobile communication device and not just future smartphones.
“The radio will learn from past behavior of the user — location, time of day, other wireless networks it sees — what might be the user's intentions,” he said.
“Cognitive radio technology is one of the hottest current research topics in wireless communications,” said Jayaweera. He has promoted an ambitious path for this technology over the last several years. “These radios are not only intelligent and autonomous but are also self-aware,” said Jayaweera.
Jayaweera said that a self-aware radio is one that uses signal processing (machine learning) to make sense of its radio frequency (RF) environment and then uses that knowledge to make decisions on how best to meet the user’s needs. Cognition and intelligence in radios reside in the machine learning algorithms that are embedded within them . The development of those processing and learning systems are the focus of his research.
Jayaweera is quick to downplay any Orwellian associations. “[It is] a wireless communications device that can make its own decisions based on its past experiences. That is all. Since it can make its own decisions on how to operate, it is autonomous. For the same reason, it is like a robot. But since this is a radio, it is a radio+robot = radiobot, ” he said.
There is a great demand for cognitive radio technology. “There are many research groups, government agencies and companies attempting to develop smart radio systems and networks that can quench the seemingly never-ending thirst for anywhere, anytime, anyhow wireless communications,” he said.
Jayaweera just finished writing a book titled “Signal Processing for Cognitive Radios” that is to be published by John Wiley & Sons, in early 2015. It will highlight the fundamental importance of signal processing to cognitive radios.
Jayaweera was born in Matara, Sri Lanka. After completing his high schooling, he worked as a science journalist till 1993 at the Associated Newspapers Ceylon Limited. He left Sri Lanka that year, and in 1997, he received the B.E. degree in Electrical and Electronic Engineering with First Class Honors from the University of Melbourne, Australia.
Jayaweera received his M.A. and PhD degrees in Electrical Engineering from Princeton University, USA in 2001 and 2003, respectively. He joined ECE@UNM as an Assistant Professor in 2006 where is now an Associate Professor and the Associate Chair and the Director of Graduate Program.
Caption for figure shown above: Cognitive radios can not only detect signals but also identify what they are. For that, they are capable of extracting certain inherent features of different signals.
Tarief Elshafiey Teaches “Engineering Sense”
By Charles Reuben — September 1, 2014
“Engineering is a way of life, not just a profession,” said ECE professor, Tarief Elshafiey.
Elshafiey taught three classes this summer and each one was filled to capacity
Grant Heileman, a student in Signals and Systems last summer and now studying Power Systems with Elshafiey spoke enthusiastically about his professor.
“His exuberant personality and enthusiasm towards the subject matter, as well as the well-being of his students, gave me much needed positive reinforcement for such difficult classes,” said Heileman.
Because of the difficulty of the class, Elshafiey offers his Communication Systems students extra credit opportunities.
One of the extra credit projects was to build a radio. Students were awarded five points if their radio received one channel plus up to ten points for each additional station the radio received.
Excitement about his extra credit project caught the professor off guard, “It was a surprise for me when 15 students out of 27 applied for the project because a significant amount of time and effort is required to achieve a functional radio in only four weeks,” said Elshafiey.
“The idea of the project,” said Elshafiey , “was to build an AM radio using envelope detection, which is considered the simplest demodulation technique.”
There were five constraints for the project:
No IC or amplifiers were allowed.
The radio had to be built using discrete components like diodes, resistors and capacitors.
The radio had to have the capacity to receive more than one channel.
Students had to design and build an antenna for the required frequency range.
A breadboard and wires were allowed.
The students went above and beyond Elshafiey’s expectations.
“Students came up with amazing ideas to tune the radio and wonderful shapes for the antennas even though they had not taken the antenna course yet,” said Elshafiey.
It’s not easy to build a radio from scratch. Some students like Justin Johnson even put time in during the weekend.
“Justin met me in the weekend at my office with his wife to find an explanation why the radio did not work here in the ECE building and works great at home, ” said Elshafiey.
Despite the extra time required by the project, Johnson found it beneficial to his understanding of the course material.
“Building the device itself was not difficult, but to obtain a clear, audible signal did require some effort,” said Johnson, “[Elshafiey’s] coupling of theory with a hardware project really helped to bring things together for me.”
Elshafiey marvels at his students, “Most of them have multiple responsibilities; studying, working part time or even full time and some of them have families and kids, this is really amazing,” he said.
Elshafiey seems to understand that engineers have a unique way of looking at life, something he likes to call “engineering sense.” He summed it up this way, “If you are a poet and I am an engineer and we are both buying a new car, you might say this car has a beautiful shape and wonderful romantic, red color. I, on the other hand, would say it is reliable and has good MPG.”
How do you spell success? Try A-M-E-R-E-M
By Charles Reuben — August 15, 2014
The AMEREM 2014 High Power Electromagnetics conference wrapped up its work on July 31 after a four-day run in the auditorium and meetings rooms of the UNM SUB.
"We had 175 attendees from 25 countries," said Edl Schamiloglu, ECE professor and conference general chair, "I received only positive comments from people regarding the technical sessions, the tours, the reception and the awards banquet."
AMEREM was the creation of Dr. Carl E. Baum who served as Distinguished Research Professor at ECE from 2005 until his death in 2010. The conference is a gathering of scientists and engineers whose name is coined from the word America and the abbreviation for “electromagnetics” (EM).
“Although there are many conferences that cover electromagnetics, AMEREM is uniquely focused on High Power Electromagnetics,” said Schamiloglu. “UNM came across first class”
Baum fashioned another EM conference in Europe known as EUROEM: The two conferences alternate between North America and Europe so there is an electromagnetics conference taking place every four years in each continent. At this year’s AMEREM it was announced that yet another electromagnetics conference will be held for the first time in Asia on Jeju Island, South Korea. And this, of course, will be called ASIAEM 2015.
“Although there are many conferences that cover electromagnetics and aspects of electromagnetics, the AMEREM, EUROEM, ASIAEM series is uniquely focused on High Power Electromagnetics,” said Schamiloglu, “This is an important technical area in the State of New Mexico since Sandia National Laboratories, Los Alamos National Laboratory, the Air Force Research Laboratory, and the University of New Mexico all have important programs dedicated to High Power Electromagnetics.”
To ECE graduate student Julie Lawrence, Baum's last PhD candidate before he passed away, presenting her paper at AMEREM 2014 was especially poignant.
"I wish Carl Baum were still alive to see the work that I am doing now. I miss his presence and extensive knowledge. Presenting at this conference gave me an opportunity to get invaluable feedback from my peers," she said.
Not all the presenters at the conference were seasoned veterans or professional engineers. Undergraduates Sydney Horne and Ahmed ElShafiey presented a poster at the conference on the subject of "EM Fields Produced from Over-Voltaged Spark Gaps." Both students work under the guidance of Research Professor Sal Portillo.
"This was my first poster presentation," said Horne who is a junior studying biophysics, "This was an excellent growth and learning opportunity for me."
"This conference gave me the chance to design circuits and simulate them which allowed me to gain experience in my field of study," said ElShafiey, a sophomore at ECE, "I made a lot of great connections that I can hopefully collaborate with in the future."
Ryan Hoffman, an attendee from the Office of Naval Research in Arlington, VA found the conference to be unique, “I was impressed by the fundamental nature of the work compared to most other conferences in this area.” Peter Zwamborne, from the The Hague, Netherlands said, “I return home with a lot of new ideas and scientific inspiration provided during the presentations and follow up discussions with my friends.”
Thanks to the support of ECE and others, AMEREM’s success and will be an inspiration to engineers and scientists entering the field of High Power Electromagnetics.
“UNM came across first class,” said Schamiloglu.
The following is a photographic record of the events that occurred at AMEREM 2014:

Mancuso Says FE Exam Opens Doors for Grads
By Charles Reuben — August 8, 2014
When Tony Mancuso sets his mind on doing something, it’s pretty much as good as done.
The big difference between Mancuso and most students is that he entered ECE at age 46, making him a “non-traditional student.” He is now part of a team in Alaska that is responsible for the design, maintenance and upgrades of the state’s communications system.
“I worked hard [at ECE] and had the benefit of experience and wisdom — things my classmates worked without,” said Mancuso. “It was great to compete and collaborate with my ECE friends. I was inspired by their questioning of everything and their persistence in finding answers.”
Though Mancuso enjoyed his previous career, his desire to learn motivated him to go back to school.
“I liked the work but there were many things I wanted to understand that could only be learned through study,” said Mancuso.
In his three years at ECE Mancuso earned his Bachelor of Science degree in Electrical Engineering (BSEE) as a full-time student while working as an intern at Sandia National Laboratories.
He graduated in May 2014 and started working for the State of Alaska in July 2014.
Tony recommends that graduates take the Fundamentals of Engineering Exam (FE). It is a $225 test, which is the first step in the process leading to the Professional Engineer (PE) license.
Just like becoming a CPA defines an accountant and "passing the bar" allows a student to practice law, a PE gives a person the authority to sign and seal engineering plans and provide services to the public.
“I learned that the FE Exam certifies an engineering graduate to serve as an engineer in training and is the first step in obtaining a PE license,” said Mancuso.
Mancuso is well on his way to becoming a professional engineer now that he has earned his BSEE and has passed the FE and he’s working as hard as ever. He’s even considering an EE-masters program in atmospheric effects on electromagnetic wave propagation.
“I thought things would slow down after school but after a slow and peaceful drive to Alaska, the pace is nice and fast, just as I need it. Living the dream,” he said.
UNM and UC3M Sign Double Degree Program
The UNM Provost Chaouki Abdallah and the President of Universidad Carlos III de Madrid (UC3M), Daniel Peña, have signed a double degree program agreement within both universities together with the UNM Electrical and Computer Engineering Department and the UC3M School of Engineering.
The agreement allows UNM students pursuing an M.S. in Electrical and Computer Engineering to also obtain an M.S. in Telecommunications or Multimedia and Communications at UC3M in Spain. Students of UC3M pursuing one of these degrees in Spain, can also obtain an M.S. in Electrical and Computer Engineering from UNM.
UNM students wanting to obtain a Master in Telecommunications must pass 30 credit hours corresponding to one of the ECE paths, and then spend a year at UC3M, where they need to take four specific courses, taught in English, an d complete their Masters’ thesis.
Manel Martínez-Ramón, Prince of Asturias Endowed Chair at UNM and Ramiro Jordán, Associate Professor, have been working to establish relationships between UNM and UC3M. Martínez-Ramón says that though classes will differ from the courses that would be taken at UNM, they will enrich students’ education.
“This is actually good because they will acquire knowledge in courses that have been developed with different objectives, to educate professionals with profiles that are quite different from the ones of the university of origin,” said Martínez-Ramón, “This will broaden the capacities of the students, and their scope.”
In addition to educational enrichment, this program will help students to develop new perspectives.
“I wish I had a penny for each time I heard, ‘In this country people live better than in any other,’ in Spain, the USA, France, Germany, and in other countries,” said Martínez-Ramón, “Living abroad makes you get rid of the concepts ‘better’ and ‘worse’ to adopt concepts like ‘different.’”
Martínez-Ramón also says that this exchange program will benefit students on the UNM campus.
“Studying abroad is not only a benefit for those who travel, but also for those who host the students,” said Martinez-Ramon, “Talking, living and sharing things with foreigners of any country is always an enriching experience that benefits the society.”
This is an opportunity for UNM students to obtain an additional M.S. valid in Europe, and to get immersed in the culture and language of Spain.
Students who are interested in joining the program should contact either Manel Martínez-Ramón or Ramiro Jordán.
Christodoulou, Blaunstein Pen Second Edition
By Charles Reuben — July 15, 2014
Nothing spells sweet success like a second edition, especially in academia where textbooks aren't selling like hotcakes. This feat is particularly noteworthy when the subject matter is microwaves — which can hardly be called light reading.
The book was published by John Wiley & Sons, a global publishing company founded in 1807 that specializes in academic publishing. According to Kai Chang, editor of the Wiley Series in Microwave and Optical Engineering, which included Christodoulou’s book, the book was originally published in October 2006 and several thousand of them have been sold to “professional people and for classroom use as a textbook.”
Chang, who also serves as a professor at Texas A&M University said that Christodoulou’s book is “a very good book [and] has lots of theoretical background for people working in this area. It also has practical applications.”
The first edition of the book was very popular among radio engineers and designers of wireless communication links because it allowed them to predict grade of service, quality of service and the information data rate that passed each individual link.
Christodoulou co-authored the book with Nathan Blaunstein, a professor at the Communication Systems Engineering Department at Ben-Gurion University of the Negev, Beer Sheba, Israel. Christodoulou and Blaunstein shared the responsibility of writing the book equally.
“I wrote chapters regarding radio propagation in different media and on various wireless systems,” said Blaunstein, “Christos dealt with chapters and parts of chapters regarding antennas and their applications in various wireless systems.”
“Christos was the first who understood the usefulness of such a unified technique for successful applications in wireless communication systems beyond 3-G (4-G and more),” said Blaunstein
Blaunstein left the former USSR in and immigrated to Israel in 1992. He first met Christodoulou in Calfornia in 1995. “He asked me a lot of questions on my report regarding radio propagation scenarios in built-up communication environment. He first suggested for me to use a general theory of radio wave propagation, based on statistical and quantum electrodynamics, in specific engineering fields, mostly for adaptive/smart multi-beam antennas applications.”
Christodoulou has worked with Blaunstein for over 10 years. UNM and Ben-Gurion University have a Memorandum of Understanding (MOU) on mutual scientific and educational collaboration.
Blaunstein said that his collaboration with Christodoulou has lead to important findings that will be added to the book in the new second addition.
“Christos was the first who understood the usefulness of such a unified technique for successful applications in wireless communication systems beyond 3-G (4-G and more),” said Blaunstein, “Obtaining very serious, practical results with him, we decided to introduce these very important results in the second edition of our joint book.”
No doubt these results in the second edition of their book will be hailed with as much fervor as those presented in the first edition.
Deconstructing (and Revitalizing) the ECE Dept.
By Charles Reuben — July 1, 2014
There’s change (and dust) in the air at the ECE building these days. A lot of these changes are due to construction, but some of them are much more subtle. And that’s where ECE’s new marketing director, Sarah Lynas, comes in.
Lynas was a student at the Communication and Journalism Department who was recently hired by chair Jane Lehr after she presented a campaign to enhance the image of ECE as part of a class project.
Tired, old display cases and worn-out chairs have been sent to salvage and the walls are being patched and prepped for a long-overdue new coat of paint.
“The goal of the new campaign is to increase enrollment and revitalize the department’s image,” said Lynas, “as well as to really showcase who engineers are at ECE and what they’re doing.”
Lynas is a senior studying strategic communication and applied math. She hopes to help create a new, cohesive image for the department.
Lynas has discovered that our ECE students are doing a lot more than just hitting the books. ECE students write poetry, snowboard, and so much more, she is eager to showcase these talents. On Thursday, May 27, the first poster from the new campaign went up in the ECE foyer. The new poster showcases the work of graduate student, Gangadharan Esakki.
She is also hard at work on a poster that features the talent of our resident snowboarder, Grant Heileman.
Other changes at ECE are happening to the building itself. The department is determined to make the building a more comfortable and efficient place to work and study.
High efficiency LEDs have taken the place of fluorescent tubes in dark stairwells.
“They are Lithonia’s premier fixtures,” said electrician Ryan Ralson.
Each fixture costs about $120 and he has installed 100 of them in the building. The renovations are being paid for by UNM.
“The new lighting should pay for themselves in energy savings fairly quickly,” said Ralston.
Classrooms and offices light up after a person passes through a doorway making old-fashioned light switches a thing of the past. The new switches are wireless.
Contractors are tearing out old ductwork and replacing them with new and shiny, digitally controlled air handlers that will improve the building’s heating and cooling.
According to David Modisette, the building manager and part-time ECE instructor, changing out the building’s “air flow routing” is a work in progress and it will take some time before the work is completed.
“I think the construction workers are doing as well as possible, given that the building is occupied,” said Modisette, “When this is completed there will be significant energy savings and people will have better control over their work space temperature and lighting. The new vents will also eliminate the loud banging caused by the old baffle actuators.”
Modisette’s third floor office is a chilly 66 degrees while the temperature in the first floor offices is so hot that many of the staff have set up temporary fans that were leftover from a previous building crisis.
“That’s because the HAC guys are installing the ductwork,” said Ralston. “After that’s done, we’ll install the electrical power that the control guys will use for the systems that control the air conditioning. And then UNM will be able to control the building remotely.”
Modisette and Ralston said all these changes to the building will be completed at the end of July.
Robot Fiesta: Daryl Lee Makes It Look Easy
By Charles Reuben — June 15, 2014
Over 60 students crammed into the ECE118 conference room on Thurs., May 14, 2014 for Robot Fiesta. Their mission: To show how their little androids can successfully and independently, follow one of three paths that were taped out on a conference table. The awards were bragging rights and a grade.
The professor was Daryl Lee, a lecturer at ECE, and the class was “Fundamentals of Programming, “ECE 131. This joyous, and somewhat chaotic event, took place on the final exam day.
“We use robots for the primary purpose of showing the students how quickly they can get into programming electromechanical devices, and not be stuck with just printing text to a computer screen,” said Lee.
His expectations were high but Lee understands, better than most, how difficult this task really is. When asked what these robots were supposed to do, he joked, “They’re supposed to not fall off the table.”
During his free time, Lee sings in "Quintessence-Choral Artists of the Southwest." He likes to compare the software engineer’s task to that of a concert pianist.
“(Our job) is to make fairly complex work appear easy . . . The computer cannot read our minds; we must be very specific about every little thing, ” said Lee.
That task is daunting and the work of a software engineer can be frustrating but Lee said the rewards are huge.
“When the switch is flipped on, and that little monster begins following the path, the feeling of success is unbeatable,” said Lee.
After four years of teaching, Lee still enjoys watching his students’ robots.
“I've worked on devices of much higher levels of sophistication. Even though I still get a rush when some new software works right, every semester I'm reminded of what it feels like to slay that first dragon. The looks on the students’ faces are its own reward,” said Lee.
As the robot fiesta drew to an end, a frustrated student complained that her robot was moving much too slowly down its path. Lee responded by saying that despite that fact, the robot was on course and moving “nice and smooth.”
“Well,” conceded the student, “I guess it works . . .”
“There’s a lot to be said for that,” said Lee. —by Charles Reuben
Md. Mottaleb Hossain Wins 2K and Prestige in Optics and Photonics Education Scholarship
Md. Mottaleb Hossain, a CHTM and OSE-ECE graduate student, has won the prestigious 2014 Optics and Photonics Education Scholarship from the International Society for Optics and Photonics. He was awarded $2,000 for his potential contributions to the field of optics and photonics.
Mottaleb has been a mentor to a number of undergraduate and high-school students working on research projects at CHTM. He has donated his time generously to many outreach activities at CHTM and OSE.
Mottaleb received Bachelor of Science (BSc) in Electrical & Electronic Engineering (EEE) from Khulna University of Engineering & Technology (KUET), Bangladesh in 2009. He is now pursuing PhD in Optical Science and Engineering (OSE) at UNM.
Mottaleb works with ECE Professor Majeed M. Hayat, CHTM Associate Director and OSE General Chair and Fellow of SPIE, OSA, and IEEE on modeling, design, fabrication, and characterization of CMOS compatible avalanche photodiodes (APDs) and integrated plasmonic detectors to be used in smart-lighting applications. His research work is supported in part by the National Science Foundation (NSF) under the Smart Lighting-Engineering Research Center (ERC).
Mottaleb is the newly elected President of the Optical Society of America's UNM Student Chapter (OSA-UNM) for 2014-2015. He also served as the Vice President of OSA-UNM Student Chapter for the period of 2013-2014. He is an active graduate student member of many professional and learned societies including SPIE, OSA, IEEE, IEEE Photonics Society (IPS), IEEE EDS, and Institution of Engineers, Bangladesh (IEB). —by Charles Reuben
Poster Session in ECE Lobby Prepares Students
Poster sessions can usually be found at most scientific conferences but now, thanks to a couple of energetic ECE professors, they are becoming a regular feature in our department.
Ten teams of four students squeezed into the lobby of ECE on May 1 to show off their posters to the rest of the community. This poster session marked the culmination of 32 weeks of instruction in the Senior Design class taught by Edward Nava, professor at ECE.
They were joined by the 10 member team of the newly instituted, multi-disciplinary Senior Design class taught by Dr. Rich Compeau.
“Students will be making posters for the rest of their careers and displaying them at conferences and meetings,” said Nava. “As professional engineers, they will need to clearly summarize their work to people who are unfamiliar with it.”
The Senior Design course teaches students how to make posters and communicate their projects within a 24”x36” space. Students also learn to work in teams whose members have a variety of different technical backgrounds.
“The Senior Design course teaches students how to apply their technical skills to real-world problems,” said Nava. “They learn how to plan and manage projects that are more extensive than the typical course assignments that they have experienced thus far.
“The key to success of this program is having sponsors who are willing to pose technical problems to the teams and provide technical guidance. We are fortunate to have support from local firms, but there is always a need for additional sponsors.”
Nava encourages organizations to contact him if they would like to sponsor a project for future senior design classes. He can be reached by e-mail at firstname.lastname@example.org. —by Charles Reuben
“Swap” Wins UNM Sigma Xi Excellence Award
Swapnadip Ghosh, a fourth year doctoral student at ECE, has won the “Excellence in Graduate Research Award” from the UNM Chapter of Sigma Xi.

Siva Patibandla is a Graduate electrical engineering student with an emphasis in power and energy. He worked on the Solar decathlon, which brought in collegiate teams from all around the world to design sustainable, smart housing. He helped to design and deploy the photovoltaic system and the control system of the house that the UNM team built. Siva presented his work at the 2013 American solar energy society held in Baltimore. He also conducted a test on the Microgrid at the Solar Decathlon village with a team of engineers that was lead by ECE Prof. Olga Lavrova.
“What made this a unique test is the fact that there was 100% PV penetration,” said Siva. His work was submitted to the IEEE Transactions on Smart Grid Issue on Distributed Energy Management Systems. He is also simulating the Microgrid in two different softwares: OpenDss and ETAP. Siva strives to understand the effects of electric car integration in to the grid in the near future and his aim is to work in the renewable energy industry once he graduates.
“Ground State” Business Plan Wins $20,000
Five ECE students won second place in the UNM Business Plan Competition that recently took place at the Anderson School of Management.
The ECE students were Justin Johnston (BS EE), Conrad Woidyla (BS Comp E), Alexandria Haddad (MBA & BS Comp E), John-Mark Collins (BS Comp E), and Julian Lucero (BS Comp E). Michelle Urban (MBA from Anderson) was also part of the team.
The ECE team, which calls itself “Ground State,” competed against 12 other teams in a University-wide competition. They presented their business plans to 40+ venture capitalists and angel investors who picked the winners.
"Creating the business plan for an engineering product idea was a great learning experience," said team member Alexandria Haddad. "It reinforced everything that we have been studying over the last four years in ECE, and put a clear perspective on the business aspect that is involved in bringing a great product to market."
Ground State is a “big data company” which, according to Creighton Glenn of ECE’s Innovation Plaza is “a company that collects information from multiple users and derives useful suggestions for better living.”
Ground State’s prize-winning consumer product is Drive Pilot™ — a device that attaches to any vehicle made after 1996 and captures driving metrics such as speed, RPM, GPS location, and throttle position which users can access in real time. This information is used to encourage safe driving behaviors for new drivers, assist small business with fleet management, and more.
Ground State won a $20,000 cash prize, $3,500 that will be used for lawyers’ services and a year of virtual office space that will all be used to accelerate the growth of their business. The team was awarded their prize at a reception and banquet at the Embassy Suites Hotel in Albuquerque.
Justin Johnston, the Chief Technology Officer of Ground State said, “We would like to thank Dr. Ramiro Jordan and Dr. Kamil Agi for the mentorship during the initial phases of exploring the business idea.
“It is exciting to have world class professors that are genuinely interested in the success of their students here in the Electrical and Computer Engineering department at UNM,” said Johnston.
Ground State also won first place in the Pitch Fiesta 2.0 sponsored by Startup New Mexico, a statewide effort led by entrepreneurs to support the growth of startups throughout New Mexico. —by Charles Reuben
Elmyra Grelle Wins the 2014 SOE Staff Award!
Elmyra Grelle, Coordinator of the Graduate Program at ECE, has won the prestigious 2013-2014 School of Engineering Staff Award. She will receive a check for $1,000 and a handsome plaque at the Student Staff Awards Banquet on Fri., May 9 from 11 am to 1:30 pm at the Centennial Engineering Center.
“The competition this year was extraordinary, making the selection process a difficult one,” said Dr. Joseph Cecchi, Dean of the School of Engineering.
Elmyra manages the application process for incoming graduate students and the degree process for those already enrolled. She advises and assists them as they navigate their way through their individual programs. She also maintains their records and processes their contracts.
"Elmyra is one of the hardest workers I know," said co-worker Yvone' Nelson. "She is always juggling multiple responsibilities and deadlines. She gives high priority to her graduate students and takes great care of them. In fact, many lovingly refer to her as their mom."
"Outside of my children, my greatest accomplishment has been making a difference in the lives of students,” said Elmyra. “I have worked with students from kindergarten to college and that's a lot of students!"
Elmyra was born and raised in Albuquerque. "I'm a two time New Mexico State alumni, carrying on a long family tradition of attending NMSU,” she said proudly.
Elmyra taught in public and private schools for 12 years before joining ECE in 2006. "I love working with the graduate students because of their desire to pursue an advanced degree, their enthusiasm about their research and their multi-national backgrounds," she said.

COSMIAC Wins America Makes Award and is Hoping to Develop a “Star Trek Replicator”
COSMIAC, a research division of the School of Engineering with strong ties to ECE, just received word that they will become part of an America Makes Award in conjunction with Lockheed Martin, Northrup Grumman and the University of Texas at El Paso.
COSMIAC will develop new and innovative projects with Additive Manufacturing — popularly known as 3-D printing. 3-D printing has grown in great strides in the past few years with a new machine costing about the same as a decent LaserJet printer.
COSMIAC stands for the "Configurable Space Microsystems Innovations and Applications Center." It promotes aerospace innovation through the reliable and responsible use of configurable technology in military and defense systems.
Craig Kief, an Adjunct Professor at ECE, is in charge of the academic programs and design services of COSMIAC. "Right now all we do is print plastic widgets, like cups, bowls and forks, not intelligent widgets,” said Mr. Kief. “What we now want to do is produce a Star Trek replicator: We want to print a radio. Not just a handle on a car, but a radio on a car!"
What makes this grant so much more exciting to COSMIAC is that it involves printing electronics into 3-D material. “3-D printing is a new industrial revolution,” said Brian Zufelt, a research engineer at COSMIAC, “Decades ago I would have had to invest tens of thousands of dollars to create a prototype. Now with 3-D printing I can design parts, enclosures and real hardware, for a couple bucks.”
Shown below right are two examples of COSMIAC’s futuristic research. These cubeset structures, which hold the electronics of a satellite, were made using 3-D printing technology by UTEP.
The first is an antenna that was printed into the wall of a spacecraft that was similar to UNM's first satellite, launched in 2013.
The second example is a solar panel that was printed into the wall of a spacecraft.
This novel form of printing helps to reduce the risk of exposed wiring being crimped or accidentally cut. It also achieves reductions in size and weight in a spaceship — which are critical to the success of aerospace applications.
America Makes, one of the sponsors of COSMIAC’s award, is focused on helping UNM grow its capabilities and strength in 3-D printing by collaborating with academia, business, non-profit organizations and government agencies.
To learn more about COSMIAC and the sort of things that they are doing over there, please check out the following video that was aired back in 2011:

ECE Professor Greg Heileman Teaches UNM’s First MOOC Class: Web Application Architecture
Imagine teaching a class in web application architecture to over 33,000 students! That’s exactly what ECE Professor Greg Heileman began doing on March 24.
Dr. Heileman is teaching a MOOC — which stands for “Massive Online Open Course” — and it’s the first of its kind to be offered at UNM.
UNM has partnered with coursera.org and 108 institutions worldwide to provide Dr. Heileman’s class to anybody who wishes to take it, free of charge. “We envision a future where everyone has access to a world-class education,” says the coursera.org website.
Students will learn on their own schedule, watch short video lectures, take interactive quizzes, complete peer graded assessments and connect with their teachers and classmates.
“This course is not about how to build a pretty web page, it's about how to build and deploy the full stack of protocols and technologies associated with a complete web app,” said Dr. Heileman.
Dr. Heilman explains the goals of his MOOC in the following video:

ECE Professor Daniel Feezell Publishes GaN VCSEL Review in Compound Semiconductor
Daniel Feezell’s six-page, full-color article entitled “The Evolving GaN VCSEL” was published in this month’s Compound Semiconductor (Vol 20, No. 1), a trade magazine based in the UK with an international print circulation of 60,000.
(A compound semiconductor is made from two or more elements — in contrast to a normal semiconductor which is made from silicon.)
This review provides an overview of progress and challenges for GaN-based vertical-cavity surface-emitting lasers (VCSELs), which typically emit light in the violet to green region of the optical spectrum. These devices are finding applications in high-density optical data storage, chemical and biological sensing, and high-resolution printing.
Dr. Feezell’s article is important because of the far-reaching exposure that his words will receive: A paper that is written at a conference only reaches a select audience. This article, however, has the potential of capturing the attention of engineers and their management on a global scale.
The Magazine Compound Semiconductor touts itself as being the “leading provider of news, analysis, opinion, information and services for the worldwide Compound Semiconductor industry since 1995.” —by Charles Reuben
Feb. 21 Solar Open House is a Dazzling Success
Over 100 people attended the ECE Solar Open House at Mesa Del Sol on Fri., Feb. 21, 2014 from noon until 3 p.m.
Upon their arrival, visitors snacked on treats and walked through the $285,000 structure.
Later, UNM President Robert Frank and Provost Chaouki Abdallah acted as keynote speakers during a ceremony held in an adjoining tent. They introduced a host of politicians and corporate dignitaries to the overflow crowd.
Known as the SHADE house (short for “Solar Homes Adapting for Desert Equilibrium”) participants in the Open House were able to study, first-hand, a luxurious structure that can produce more energy than it consumes.
Originally constructed as part of the Solar Decathalon (a collegiate competition sponsored by the US Dept. of Energy), ECE partnered with Arizona State University to form a team that designed and built the structure.
“This was the first time UNM participated in the Solar Decathlon and we are proud of the result,” said UNM President Robert Frank during his welcome and opening remarks. “(We were) working and competing shoulder-to-shoulder with other excellent Universities.” Frank then welcomed distinguished visitors from the Congressional Offices of Ben Ray Lujan and Senator Martin Heinrich.
“Students had to live in this house for 10 days, cook food, wash dishes, wash and dry clothes,” marveled Chaouki Abdallah, UNM Provost. “They also had to have heat or air-conditioning – all while being monitored for how much energy and water was being used.” Abdallah proceded to introduce officials from PNM, Sandia National Labs, Sacred Power and the developer of Mesa del Sol.
Finally, ECE Prof. Olga Lavrova thanked her students for their hard work and invited everybody present to view and learn more about the SHADE house in small groups that were guided by her pupils.
You can take an animated tour of the SHADE house by watching the following video that was created by the Anderson School of Management, IFDM and SA+P:

PhD Candidate Jose Marcio Luna Wins Amazon $21,000 Award Credit
In January 2014 ECE graduate student Jose Marcio Luna won a credit of $21,000 to carry out his experiments in the Amazon Web Services cloud.
"This award is very important for me because it indicates that I am on the right track and gives me the motivation to keep working," said Jose Marcio Luna during a recent interview.
Jose is originally from Colombia where he earned a Bachelor of Science Degree in Electronics Engineering at the District University of Bogota. He then earned a Master of Science Degree in Electrical
Engineering here, at ECE.
“I was born in the Colombian Caribbean coast which is well known for its beautiful mixture of Indigenous African and Spanish culture. These influences have shaped my ideas,
perceptions and opinions of the surrounding reality,” said Jose who arrived at ECE from Columbia in the fall of 2007.
Elmyra Grelle, ECE graduate program coordinator at UNM, has worked with Jose since he arrived here after winning the Colfuturo Scholarship to pursue graduate
“Jose is very kind, courteous and helpful to other international students and has been diligent in earning his degrees,” said Grelle.
“I’m currently working on my PhD in Electrical Engineering with a PhD minor in Applied Mathematics under the supervision of Dr. Chaouki Abdallah. In my spare time I practice
camping, hiking and rock climbing in the New Mexican mountains,” said Jose.
“My current research looks at the development of theoretical techniques to optimize the performance of computing systems by using Control Systems theory, Discrete Event
Systems(DES) theory, optimization theory and Randomized Algorithms.” —by Charles Reuben
Majeed Hayat and Sanjay Krishna Named IEEE Fellows
ECE faculty members Majeed Hayat and Sanjay Krishna have been named IEEE Fellows.
The IEEE is the world's largest technical professional society, with over 400,000 members. The IEEE was designed to serve professionals involved in all aspects of the electrical, electronic and computing fields and related areas of science and technology that underlie modern civilization. The number of Fellows elected in any given year is limited to 0.1% of the membership.
"The elevation of two of our ECE faculty in the Fellow Class of 2014 is a matter of considerable pride," said Jane Lehr, department chair. "The recognition of the outstanding technical accomplishments of Professors Sanjay Krishna and Majeed Hayat is a prestigious honor and an important career milestone."
Majeed Hayat, a professor at ECE, was recognized for his contributions to the modeling of impact ionization and noise in avalanche-photodiode devices. His research has helped ensure that consumer demand for higher data volume and speed within today’s computer networks are met.
Hayat pioneered techniques that have changed the way we look at avalanche photodiode photodetectors. His work on image-processing algorithms and thermal/spectral imaging have lead to the improvement and performance of inexpensive uncooled infrared imagers.
Sanjay Krishna, Director of the Center for High Technology Materials, joined ECE in 2001 and was recognized for his contributions to infrared detectors and focal plane arrays. His research into infrared sensing has helped firefighters locate people trapped in smoke-filled rooms and pilots find landing strips during bad weather.
Krishna's work has helped doctors non-invasively detect skin cancer, arthritis and diabetic neuropathy. His investigations into early skin cancer detection could help save millions of lives. He is best known for his development of novel midwave/longwave infrared detectors and focal plane arrays based on the quantum-dot-in-a-well design.
Both Hayat and Krishna received a beautifully matted and framed certificate bearing their names and a brief citation describing their accomplishments. They also received a congratulatory letter from the IEEE president and a gold sterling silver Fellow lapel pin with antique finish.

Dorca Lee Wins NASA/New Mexico Space Grant Fellowship
Dorca Lee, a PhD student in Dr. Rafael Fierro’s robotics lab won the NASA/New Mexico Space Grant Fellowship on December 16, 2013.
Dorca began her robotics research in July 2012, when she received an NSF grant that sent her to Brazil and allowed her the opportunity to collaborate with the computer science department at the Universidade Federal de Minas Gerais, UFMG. While there, she developed an algorithm that controls the way a large number of robots navigate an area collectively without directly specifying movements for each individual.
Dorca wrote a proposal about this work to the New Mexico Space Grant Consortium and how her project could potentially improve the way planetary exploration is done at NASA. This preliminary and promising swarm segregation algorithm won her the NASA/New Mexico Space Grant Fellowship. With this award she hopes to make improvement to her research, run lab tests, and hopefully make robotic swarms a possibility in outer space.
Dorca arrived at UNM from ETH Zurich in 2012 where she was studying electrical engineering. She has Bachelors in physics and applied math, and a Masters in electrical engineering from FSU. She plans to pursue her PhD at UNM while working with Dr. Fierro’s robotics lab.
La Cueva High School’s Gifted Mentorship Program Rocks ECE!
Eight excited high school students visited the ECE Department on November 11. These budding young scientists and engineers were part of the La Cueva High School’s Gifted Mentorship Program.
The students eagerly explored the nooks and crannies of the ECE building and also visited the plasma physics lab, the x-ray studies lab and the VLSI lab.
The high schoolers were awed by the HelCat plasma device (which looks like something out of a science fiction movie) and their curiosity was further stoked by passionate college students and professors who shared their own experiences, hopes and dreams for the future.
After the tour the students met with mentors who helped identify their interests and prepare them for an academic adventure that will begin this spring at ECE. At that time these gifted students will start working with research teams who will further nurture their interests in Electrical and Computer Engineering and prepare them for the college experience.
Edward Nava is looking forward to talking to students (or their parents) who have an interest in this unique engineering journey. Ed can be reached by e-mail at email@example.com or give him a call at (505) 277-0809. —by Charles Reuben
