Suggestions for RF Projects & Self-Study

Textbooks are a scam. Insist on OER.
Windows is a hot mess. Try Linux Mint.
MATLAB is unnecessary. Try Octave.
Outlook and Gmail are dangerous. Try Proton Mail.
Edge and Chrome are dangerous. Try Firefox.
AP is non-profit & a trusted source for other outlets.


I am an Associate Professor of Electrical & Computer Engineering at Virginia Tech (my VT web site). I am interested in antennas & propagation, applied signal processing, and RF instrumentation. My work on instrumentation includes antennas, RF electronics, digital signal processing, and software for systems with unusual or extreme requirements. I work on various aspects of radio communications and radio science. I also work on instrumentation and techniques for radio astronomy, most recently in the development of meter- and centimeter-wavelength observing systems and interference mitigation techniques.

I am also a consultant, helping government and companies with problems related to RF and antennas, geolocation, and interference mitigation; services including systems engineering and proposal development; and tailored short courses and other training materials on topics in my areas of expertise. I am not interested in expert witness/testimony or patent-related work.
