Editorial Note: This issue is part one in a three part series on the future of physical layers for RFID. In this part the following topics are covered: (1) Resurrection of the Esaki Diode: Tunneling Becomes Cool Again, and (2) Retrodirectivity for RFID: Orientation-Independent Tag Design with Gain.
I had fantastic electrical engineering teachers at Virginia Tech (my alma mater for BSEE, MSEE, and PhD). However, I consciously constructed this Georgia Tech lecture thinking, “This is the way I wish I had been taught Phasors.”

This paper presents a new device for implementing a retrodirective backscatter modulator — an antenna + RF structure that reflects microwaves back to their source, while also adding information. The technique is extremely flexible and low-power, although only practical at microwave bands when the wavelength becomes several centimeters or shorter.
