Carl Baum
The SUMMA Foundation was founded in 1973 and registered with the IRS as a philanthropic organization to promote scientific and educational activities in the field of electromagnetics. Initial funds to the Foundation were contributed by Dr. Carl E. Baum who has, from time to time, also donated the monetary parts of his scientific awards to the Foundation plus additional funds. Contributions have also been made to the Foundation by donors interested in promoting various scientific activities in the field of electromagnetics. Some of the Foundation activities have had surpluses deposited back with the Foundation.


Notes Uploaded on January 17, 2013

      On January 17, 2013 we uploaded six new contributions to the NOTE series located at www.ece.unm.edu/summa/notes.

      In SDAN 40, Kohlberg investigates the survivability of Mobil Ad-hoc Network (MANET) system by focusing on the effect of spatial inhomogeneity of node concentration. Farr extends his earlier characterization of antenna impulse response to arbitrary source and load impedances in SSN 558.

      In SSN 559, Prather describes the design, construction and operation of the Ellipticus Illuminator and shows some limited CW-to-pulse comparisons on several aircraft that were measured in both facilities.

      Vega, Rachidi and Giri present a new profile for the electrodes forming the radial transmission line of a switched oscillator (SWO) in SSN 560.

      In SSN 561, Vega et al., investigate the input impedance of an antenna driven by switched oscillator (SWO).

      Yan-zhao Xie presents an alternate analytical expression to the usual double exponential (DEXP) and the quotient exponential (QEXP) forms for the early time HEMP (E1) environment in SSN 562.

      On behalf of the editorial board of the NOTE series, I wish to thank the authors and reviewers of these publications for their contributions in keeping up the high-standards of the NOTE series set by Carl Baum.

          Happy reading!
