Supplying electrical power to these devices wirelessly would eliminate/relieve their battery life lim itation\, and therefore is envisioned to be one of the enabling technologi es for the next-generation Internet of Things. Since wireless power delive ry must be dedicated to the designated receivers in space\, it is inevitab le to employ one narrow electromagnetic beam as the carrier of wireless po wer toward each mobile device. The retro-reflective beamforming technique has excellent potential to accomplish efficient wireless power transmissio n 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 th e devices accordingly. The primary merit of retro-reflective beamforming t echnique is that wireless power transmission is augmented by radar trackin g. Specifically\, wireless power transmission is initiated by pilot signal s broadcasted from wireless power receiver(s)\; and in response to the pil ot signals\, a wireless power transmitter delivers directional microwave p ower beams to the receiver(s). This presentation reviews our past\, ongoin g\, and future research efforts on wireless power transmission based on re tro-reflective beamforming. This talk starts with the fundamental principl es and a brief history of retro-reflective beamforming technique. Next\, t he pros and cons of retro-reflective beamforming are analyzed via comparis on with other wireless power transmission techniques. Plentiful theoretica l and experimental results collected in our research demonstrate that the retro-reflective beamforming scheme enables microwave power beams to follo w the location of mobile wireless power receiver(s) dynamically as long as the receiver(s) broadcast pilot signals periodically. The last part of th e presentation discusses the challenges pertinent to the practical applica tion of retro-reflective beamforming technique.\n\nSpeaker(s): Mingyu Lu\, \n\nRoom: 4021\, Bldg: Sobrato Campus for Discovery and Innovation\, Sant a Clara University\, Santa Clara\, California\, United States\, 95053 LOCATION:Room: 4021\, Bldg: Sobrato Campus for Discovery and Innovation\, S anta Clara University\, Santa Clara\, California\, United States\, 95053 ORGANIZER:vvi4hc@virginia.edu SEQUENCE:11 SUMMARY:Wireless Power Transmission based on Retro-reflective Beamforming URL;VALUE=URI:https://events.vtools.ieee.org/m/481890 X-ALT-DESC:Description: <br /><p>With the rapid development of Internet of Things\, a vast number of small\, low-cost\, and low-power mobile electron ic devices\, such as radio frequency identification tags and wireless sens ors\, will become integral parts of our society in the near future.
