Notes Uploaded on August 19, 2013
On Monday, August 19, 2013 we uploaded six new contributions to the NOTE series.
There will be no hard-copy distribution of the NOTEs.The manuscripts that are received are reviewed, revised and uploaded to http://www.ece.unm.edu/summa/notes. You can be added (at no cost) to the postcard notification mailing list by e-mailing Chuck Reuben at shawnee@ece.unm.edu.
In IN 624, Giri and Tesche report on measurements and modeling of attenuation through building materials. PhN 21 is an interesting contribution from Ian Gallon which considers equation of motion of point charges and resulting radiation.
MN 64 is a comprehensive manual by Tesche on CW Testing including test planning, equipment needed, measurement techniques and assessment. In SSN 563, Singh et al. consider an asymptotic conical dipole (ACD) type of feed for the reflector HIRA eliminating the need for a balun.
In SSN 564, Farr extends his earlier work on the theory of antenna radiation and scattering into the time domain a number of standard antenna terms, including gain, antenna factor, antenna pattern, beamwidth, scattering cross section, and radar cross section. Singh et al. work out the performance of the reflector IRA with an ACD type of feed in SSN 565 and demonstrate the advantage of the ACD feed over the conventional feed.
Harmouch and Haddad consider slotted waveguide antennas in a ring shape and report their innovative approach in SSN 566. Finally Singh et al. use the conjugate gradient (CG) method in calculating the impulse response of hyperband antennas in SSN 567. The CG method in time domain appears to offer some advantage over the conventional Fourier Transform method.
