Radio Systems Engineering Electromagnetics Vol. 1
I am interested in antennas & propagation, applied signal processing, and instrumentation. My work on instrumentation includes antennas, RF electronics, digital signal processing, and software for systems with unusual or extreme requirements. I also work on various aspects of mobile radio communications. I am active in radio astronomy, most recently in the development of meter- and cm-wavelength observing systems and their application in cosmology, pulsars, and astrophysical transients. I advise students in the "Electromagnetics" and "Communications" areas of our department.
