Abstract:
An EMI shield for a wireless power transmitter is presented. The EMI shield includes a patterned metallic layer that when positioned over a transmitting coil of the wireless power transmitter capacitively couples to the transmitting coil to capture electromagnetic radiation while allowing magnetic power to pass. In some embodiments, the patterned metallic layer may be a comb filter.
