According to some implementations, an apparatus for transmitting charging power wirelessly to a load is provided. The apparatus comprises at least one ferrite structure comprising a first ferrite portion, a second ferrite portion comprising at least a first ferrite leg, a second ferrite leg, and a third ferrite leg, each physically separated from the first ferrite portion by a first distance, and a third ferrite portion positioned between the second ferrite leg and the first ferrite portion and physically contacting the second ferrite leg. The at least one ferrite structure further comprises a coil wound around the second ferrite leg and configured to generate an alternating current under influence of an alternating magnetic field.
