Power provision scheme considering shadowing effect for two-dimensional communication systems

Two-dimensional communication system (2DCS) is a novel communication system which utilizes surface of sheet as communication medium. 2DCS provides wireless power supply as well as safely and high-speed data transmission to sensor devices. However, how to suppress the standing wave effect to a minimum is still an open issue for 2DCS. In this study, we explore how the power distribution on sheet medium changes by the location of input coupler, and then compose a scheme of the power provision with multiple single or compound couplers where shadowing effect is considered to suppress the standing wave effect. Through simulation experiments, we evaluate the performance of proposed scheme to improve the power provision efficiency over 2DCS.
