This disclosure provides systems, methods and apparatus for mitigating electromagnetic radiation emissions. In one aspect, a power transfer device of a wireless electric vehicle charging (WEVC) system is provided. The power transfer device includes a ferrite material and at least one electrically conductive coil. The ferrite material and the at least one coil are configured to wirelessly transfer energy either from or to a second power transfer device of the WEVC system. The power transfer device further includes at least one shield comprising a plurality of electrically conducting regions and one or more electrically insulating regions. The plurality of electrically conducting regions and one or more electrically insulating regions are configured to mitigate electromagnetic radiation emissions from the WEVC system that do not contribute to the wireless power transfer between the at least one electrically conductive coil and the second power transfer device.
