Abstract
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.

A contactless power transfer system comprising:
- a first coil configured to produce a magnetic field;
- a second coil configured to receive power from the first coil via the magnetic field;
- and
- a field focusing element comprising a plurality of resonators arranged in an array, wherein 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.
A contactless power transfer system comprising:
- a field focusing element comprising a plurality of resonators arranged in an array, wherein the array comprises an active array configuration, a passive array configuration or a combination thereof and the plurality of resonators interfere constructively in a desired direction and interfere destructively in a remaining space to focus a magnetic field based on the configuration of the array.
