Abstract
Electronic wireless equipment will produce electromagnetic interference, which can affect the surrounding environment and the normal operation of other equipment. This paper builds basic model of wireless energy transmission and electromagnetic shielding model, and analyzes the influence of structure and material of electromagnetic shielding to the wireless energy transmission system based on finite element method. The simulation results indicate that the electromagnetic field attenuates effectively after the addition of shielding body, and the shielding effect of the semi-enclosed structure is slightly better than the flat plate structure under the same power supply and system frequency. With the increase of coil distance, the smaller the receiving current is, the worse the shielding effect is. Ferrite is a magnetic shielding material, while metallic aluminum is an electrical shielding material. Adding ferrite will increase the magnetic induction intensity between coils, while adding aluminum plate will reduce the magnetic induction intensity between coils.
