Abstract
In this paper, a novel resonant reactive shield using modified phase shifter to reduce the magnetic field leakage for wireless charging electric vehicle is proposed. The proposed shield generates the cancelling magnetic field of which phase is completely opposite to that of incident magnetic field. By simulation, it is verified that the proposed reactive shield has significantly improved shielding performance compared with a previous resonant reactive shield.
