In this lecture of the Wireless Without Batteries series, we discuss the basics of modeling antennas in circuits --both in transmit mode and receive mode. Below is a reading list corresponding to the material. WWB02: Antennas in Circuits for … [Continue reading]
Here is a "stealth" electromagnetic design problem. Hint: The problem isn't that hard if you view the system as a cascade of TEM transmission lines rather than dielectric slabs. A Smith chart might help. … [Continue reading]
Ever had trouble navigating the Byzantine nomenclature for RF frequency bands used by engineers? I though I would post a link to this helpful chart, which my students have found helpful in the past. Download the following RF band chart. … [Continue reading]
Mike Varner recently returned from Kalamata, Greece, where he presented original research on the use of perfect pulses for scattering low-powered digital signals onto existing radio transmissions (often referred to as ambient communications or … [Continue reading]
