Receiver localization for a wireless power transfer system with a 2D relay resonator array

A magnetic resonance wireless power transfer (WPT) system using a 2D relay resonator array has been proposed. To make practical use of this system, the powering paths to the receiver devices need to be created automatically. This paper presents a receiver localization method suitable for the 2D WPT system. The feasibility of this method is evaluated by both simulation and experimentation. Moreover, we have implemented a demonstration system that automatically localizes the receiver, establishes the route, and transmits the power.
