A contactless power transfer system is provided. The system includes a first coil configured to produce a magnetic field. The system also includes a second coil configured to receive power from the first coil via the magnetic field. The system further includes a field focusing element. The field focusing element includes a plurality of resonators arranged in an array. Each of the plurality of resonators, upon excitation, interfere constructively in a direction of the second coil and interfere destructively in a remaining space to focus the magnetic field onto the second coil and enhance the coupling between the first coil and the second coil. |
