A metamterial-based cavity resonator using artificial magnetic conductor surfaces is presented and applied to realize a wireless charging system of mobile handset. This wireless charging system demonstrates the advantages of broad bandwidth, small size, long transmitting range, high transferring efficiency and EMI-free feature. The holistic architecture of wireless charging system for a smartphone is established to experimentally validate the usefulness of the metamaterial cavity resonator.
