Supplying electrical power to these devices wir elessly would eliminate/relieve their battery life limitation\, and theref ore is envisioned to be one of the enabling technologies for the next-gene ration Internet of Things. Since wireless power delivery must be dedicated to the designated receivers in space\, it is inevitable to employ one nar row electromagnetic beam as the carrier of wireless power toward each mobi le device. The retro-reflective beamforming technique has excellent potent ial to accomplish efficient wireless power transmission in the context of Internet of Things\, as it is capable of keeping track of multiple mobile devices and then generating wireless power beams to the devices accordingl y. The primary merit of retro-reflective beamforming technique is that wir eless power transmission is augmented by radar tracking. Specifically\, wi reless power transmission is initiated by pilot signals broadcasted from w ireless power receiver(s)\; and in response to the pilot signals\, a wirel ess power transmitter delivers directional microwave power beams to the re ceiver(s). This presentation reviews our past\, ongoing\, and future resea rch efforts on wireless power transmission based on retro-reflective beamf orming. This talk starts with the fundamental principles and a brief histo ry of retro-reflective beamforming technique. Next\, the pros and cons of retro-reflective beamforming are analyzed via comparison with other wirele ss power transmission techniques. Plentiful theoretical and experimental r esults collected in our research demonstrate that the retro-reflective bea mforming scheme enables microwave power beams to follow the location of mo bile wireless power receiver(s) dynamically as long as the receiver(s) bro adcast pilot signals periodically. The last part of the presentation discu sses the challenges pertinent to the practical application of retro-reflec tive beamforming technique.\n\nSpeaker(s): Mingyu\, \n\nRoom: McFawn Room\ , Bldg: Mile 2 Mission Delivery Center (Wright Point III Office Building)\ , 5000 Springfield Street\, Suite 100\, Dayton\, Ohio\, United States\, 45 431\, Virtual: https://events.vtools.ieee.org/m/565622 LOCATION:Room: McFawn Room\, Bldg: Mile 2 Mission Delivery Center (Wright P oint III Office Building)\, 5000 Springfield Street\, Suite 100\, Dayton\, Ohio\, United States\, 45431\, Virtual: https://events.vtools.ieee.org/m/ 565622 ORGANIZER:tswolfe@ieee.org SEQUENCE:21 SUMMARY:Wireless Power Transmission based on Retro-reflective Beamforming URL;VALUE=URI:https://events.vtools.ieee.org/m/565622 X-ALT-DESC:Description: <br /><p><strong>*<em>I</em><em>EEE Distinguished M icrowave Lecturer: Mingyu Lu*</em></strong></p>\n<p>&nbsp\;</p>\n<p>With t he rapid development of Internet of Things\, a vast number of small\, low- cost\, and low-power mobile electronic devices\, such as radio frequency i dentification tags and wireless sensors\, will become integral parts of ou r society in the near future.
