DESCRIPTION:With the rapid development of Internet of Things\, a vast numbe
 r of small\, low-cost\, and low-power mobile electronic devices\, such as 
 radio frequency identification tags and wireless sensors\, will become int
 egral parts of our society. Supplying electrical power to these devices wi
 relessly would eliminate/relieve their battery life limitation. Since wire
 less power delivery must be dedicated to the designated receivers in space
 \, it is inevitable to employ one narrow electromagnetic beam as the carri
 er of wireless power toward each mobile device. The retro-reflective beamf
 orming technique has excellent potential to accomplish efficient wireless 
 power transmission in the context of Internet of Things and can track mult
 iple mobile devices\, generating wireless power to the devices accordingly
 . The primary merit of retro-reflective beamforming technique is that wire
 less power transmission is augmented by radar tracking. Specifically\, wir
 eless power transmission is initiated by pilot signals broadcasted from wi
 reless power receiver(s)\; and in response to the pilot signals\, a wirele
 ss power transmitter delivers directional microwave power beams to the rec
 eiver(s). Results collected in our research demonstrate that the retro-ref
 lective beamforming scheme enables microwave power beams to follow the loc
 ation of mobile wireless power receiver(s) dynamically when the receiver(s
 ) broadcast pilot signals periodically.\n\nSpeaker(s): Dr. Mingyu Lu\n\nRo
