Design principles and implementation of receiver positioning and beam steering for laser power transfer systems.

Laser power transfer (LPT) is an emerging technology that can provide convenient and long-range wireless power to the ever-expanding array of electronic devices. One of the biggest challenges in implementing LPT systems is to realize receiver positioning and beam steering (RPBS) for directing power toward the intended target which, however, have only been investigated by a few studies. Herein, a set of design principles is proposed, intended to assist researchers in developing systematic schemes for RPBS.
