The fundamental question answered by our backscatter radio research program is what is the minimum possible energy that a communication node must expend to transfer information wirelessly? The more you understand about conventional wireless communications, the more the answer will surprise you. [Read more…]

This paper explains how to build a transparent rectenna farm cheaply. The ability to cover square kilometers with expensive, transparent microwave harvesting circuitry — and re-using the land for agriculture, for example — is a key to making space solar power affordable.

This was our first foray into space solar power. Teaming up with Darel Preble of the Space Solar Power Institute and Frank Little of Texas A&M, the 2011 ECE 6390 Satcom students put on a fantastic show of their work.
Buried in the time domain instructional series on the YouTube channel is one of my favorite lectures on nonlinear transmission line loads. The last portion of this lecture is original content on time-domain transmission lines terminated with nonlinear, active loads such as tunnel diodes. Even a transmission line can generate a chaotic bifurcation diagram.
