Abstract

We propose the concept of and experimentally demonstrate a metasurface-based smart table for wireless power transfer. The proposed structure supports propagating surface modes that can be excited by the near field of wireless devices. As a result, if two devices are placed anywhere on a metasurface table, a substantial enhancement of the effective near-field coupling can be achieved. This enhancement leads to a demonstrated power-transfer efficiency of 80% for the receiver placed in any location with respect to the transmitter on the table. The proposed concept enables a variety of applications from consumer electronics to charging electric cars.
