摘要

将人工周期结构组成的超材料应用于无线电力传输系统中，提高了远程电力传输的效率。超材料由于具有负磁导率，可以控制磁场方向。以前报道的超材料太厚，尺寸太大，无法增加电力传输距离。本文提出了超薄(0.16 cm)和小(18.6 × 18.6 cm)的超材料结构，并证明了其效率的提高(最大提高44.2%)。在此基础上，提出了复杂超材料结构仿真的简化建模方法。

Ultra-thin printed circuit board metamaterial for high efficiency wireless power transfer

Metamaterial composed of artificial periodic structure is applied to a wireless power transfer system to enhance the efficiency of long distance power transfer. Metamaterial can control the direction of magnetic fields due to its negative permeability. Previously reported metamaterials were too thick and large in size to increase the power transfer distance. In this paper, ultra-thin (0.16 cm) and small (18.6 × 18.6 cm) metamaterial structure is proposed and its enhanced efficiency (with maximum of 44.2 % improvement) is demonstrated. Furthermore, this paper shows simplified modeling method for complicated metamaterial structure simulation.
