Designed by Greg Koo and Albert Lu, this microwave modulator demonstrated retrodirective backscatter with 4-ary Phase Shift Keying (PSK). This would be the first of many low-powered, retrodirective designs that the group would develop. Powered by … [Continue reading]
2009: Development of the 5.8 GHz backscatter radio for high-voltage lines. This was the first big technology transfer of our microwave backscatter radio work outside of the institute. Southern states integrated this radio into their substation … [Continue reading]
Here is another installment in the "Wireless Without Batteries Lecture" series. In this lecture, we cover the use of reflection amplifier and its applications in backscatter communications links. WWB14: Reflection Amplification Reading: F. … [Continue reading]
In this lecture, we discuss the origins of retrodirectivity, starting with the Van Atta array and its use as radar chaff. We then demonstrate how to use these systems in communications links. Part of the Shenzhen lecture series on wireless without … [Continue reading]
