In this paper we present a metasurface for wireless power transfer system. The metasurface supports a surface wave, which greatly enhances the power transfer distance. In this way, WPT efficiency of 80% to a single receiver is obtained at a distance 80 cm. In addition, we show that an efficient power transfer to multiple receivers is possible. An overall efficiency of 82% can be obtained at the distance of 45 cm.
