Abstract

The technology of wireless power transfer (WPT) is used to transfer the power wirelessly through the magnetic field in the space and to charge the electrical equipment such as computer, mobile phone, electric vehicle, implantable medical devices. During the process of transmission, the radiation of magnetic field will reduce the systems’ efficiency. In order to address this problem, in this paper, a near-field plates (NFP) is designed and analyzed to interfere electromagnetic wave generated by the transmitting loop in near field, so that NFP can improve the performance of the WPT system through focusing the electromagnetic field. When the NFP is places in the WPT system, the electromagnetic field in the vertical direction of the transmitting loop will be concentrated, while the others direction of the electromagnetic field is weakened. Thus, the electromagnetic field radiation into the surrounding environment will be reduced. In this paper, the simulation results indicate that the NFP can enhance the intensity of magnetic field and restrain electromagnetic radiation.
