Abstract

In this paper a two-dimensional wireless relay plane consists of square resonant units is proposed. Power transfer between the transmitting coil and receiver above any unit can be achieved by resonance through the shortest routes on the plane. The self-resonant frequencies of units on the planned route are adjusted to be identical for efficient power transfer, while units beyond the route are isolated from power exchange due to frequency shift. Full wave electromagnetic simulation is executed and analyzed. According to the simulation results, concentrated power transfer can be realized on the power relay plane, and the highest transmission efficiency is 73.93%.
