摘　　要：This review paper is on the retro-reflective beamforming technique for wireless power applications.The primary merit of retro-reflective beamforming technique is that wireless power transmission is augmented by radar tracking.Specifically,wireless power transmission is initiated by pilot signals broadcasted from wireless power receiver(s);and in response to the pilot signals,a wireless power transmitter delivers directional microwave power beams to the receiver(s).The microwave power beams follow the wireless power receivers’location dynamically as long as pilot signals are broadcasted periodically.The retro-reflective beamforming technique therefore has excellent potential to accomplish efficient wireless power transmission to non-stationary wireless power receivers.This paper reviews the basic principles and potential applications of wireless power transmission based on retro-reflective beamforming technique.
