英文摘要：

In order to improve the efficiency of the wireless power transmission via focusing magnetic distribution, themagnetic distribution during the magnetically coupled resonant wireless power transmission was analyzed. ComsolMultiphysics simulation software was used to simulate the properties of the magnetic field of different types ofcoils and coil arrangement. The result shows that 5 coil structure designed was optimized step by step by angle,distance and size, the property of magnetic field focusing turns stronger and stronger, finally a coils structurewhich was simple and reliable was obtained.
