In this paper, a high-e┬▒ciency wireless energy transmission via magnetic resonance is implemented by using negative permeability metamaterial structures. The metamaterial structure is consisted of a three-dimensional (3D) periodic array of the unit cell that the capacitively loaded split ring resonators (CLSRRs) are periodically arranged in the cubic dielectric surfaces. This metamaterial structure has the negative permeability property that matches free space, which is used as a magnetic flux guide in order to enhance the efficiency of energy transmission between a source and distant receiving coil. The efficiency of energy transmission is improved as reducing the radiation loss by focusing the magnetic field to a distant receiving coil. The distance able to transport the energy with maintaining the same efficiency has been increased by the same mechanism. The efficiency of energy transmission is approximately 80% at a transmission distance of 1.5 m.
