摘要：

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 x 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.
