摘要：
Wireless Power transfer using electric field can realize highly efficient electrical power transmission and the transmission units are thin and light. However, the transmission system produces large electric field intensity and the electric field noise can make other electronic devices malfunction. A shield box is greatly effective to reduce the electric intensity 60dB without a decline of transmission efficiency. The distance between the shield box and the transmission unit should be a half of the transmission distance between a transmitter and a receiver. The shield box can attenuate the intensity behind the box less than 100V/m in case of 1kW transmission.
