description An apparatus for wireless power transfer includes: a support member including a charging surface configured to support a power receiving element; a power transmitting element configured to generate a magnetic field that can wirelessly transfer power to the power receiving element; a metallic shield disposed such that the power transmitting element is disposed between the support member and the metallic shield, the metallic shield being configured to inhibit the magnetic field generated by the power transmitting element; and ferrite pieces spaced apart from each other and disposed between the power transmitting element and the metallic shield and closer to the metallic shield than to the power transmitting element, the ferrite pieces offsetting an effect of the metallic shield on a reactance of the power receiving element.
