Abstract

In this paper, a sandwich structure composed of two different single negative metamaterial layers separated by air is proposed to improve the efficiency of wireless energy transfer. Numerical analysis reveals that by tuning the metamaterials, electromagnetic tunneling phenomena can occur even through a long distance over several hundred times of device length, which is far beyond mid-range. To verify the above analysis, mesh-like and double-sheet metal structures that play the roles of two different single negative metamaterials are fabricated and measured at microwave range. The experimental results show that the energy transfer efficiency, as well as the transfer distance may be superior to some conventional methods proposed previously. These features will be beneficial to the realistic application of wireless energy transfer.
