A wireless power transmitter includes a first inductive element featuring a planar coil occupying a first plane and having first and second terminals, a first capacitive element connected to the first terminal, an inverter configured to provide an oscillating voltage signal to the first inductive element, through the first capacitive element, such that the first inductive element generates an oscillating magnetic field for transmitting power in response to the oscillating voltage signal, and a layer of magnetic material, disposed over the planar coil in a second plane parallel to the first plane.
