This paper contains the designs for Francesco Amato’s tunnel diode modulator and some of the record-beating range measurements that resulted from his PhD work (5.8 GHz backscatter at up to 1.2 km). Of particular interest is the characterization of the irregular link-budget that results from these highly nonlinear devices.
Blake Marshall defended his PhD dissertation entitled, “STAGGERED PATTERN ENERGY HARVESTING AND RETRO-DIRECTIVE BACKSCATTER FOR PASSIVE RFID TAGS” on Thursday, 12 December 2017. This work invented a new class of antenna structures that exhibit retrodirectivity and optimal energy harvesting parameters. Such structures are crucial to building next-generation internet-of-things nodes, which can harvest energy and backscatter information with extraordinarily low power. Blake was a graduate of the Rose-Hulman Institute of Technology and received his MS and PhD with the GTPG. For the last several years, Blake has worked at Apple Computer in the bay area. Somehow, he found time to finish his PhD and have his first child. [Read more…]
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…]
Blake Marshall will present his PhD dissertation defense on 21 December 2017 (Thursday) in Van Leer 218 at 2pm. The dissertation is entitled, “Staggered Pattern Energy Harvesting and Retro-directive Backscatter for Passive RFID Tags.” Blake currently works for Apple Computer in the bay area.
