Abstract

Claims (19)

1. A system, comprising:

a source resonator optionally coupled to an energy source; and

a second resonator located a distance from the source resonator,

wherein the source resonator and the second resonator are coupled to provide near-field wireless energy transfer among the source resonator and the second resonator,

wherein the field of at least one of the source resonator and the second resonator is shaped using conducting surfaces to increase the coupling factor among the resonators.

2. The system of claim 1 , wherein at least one of the source resonator and the second resonator have a quality factor, Q>100.

3. The system of claim 1 , wherein the source resonator Q is greater than 100 and the second resonator Q is greater than 100.

4. The system of claim 1 , wherein the square root of the source resonator Q times the second resonator Q is greater than 100.

5. The system of claim 1 , comprising more than one source resonator.

6. The system of claim 1 , comprising more than one second resonator.

7. The system of claim 1 , comprising more than three resonators.

8. A method, comprising:

providing a source resonator optionally coupled to an energy source and a second resonator located a distance from the source resonator, wherein the source resonator and the second resonator are coupled to provide near-field wireless energy transfer among the source resonator and the second resonator, and wherein the field of at least one of the source resonator and the second resonator is shaped using conducting surfaces to increase the coupling factor among the resonators.

9. The method of claim 8 , wherein at least one of the source resonator and the second resonator have a quality factor, Q>100.

10. The method of claim 8 , wherein the source resonator Q is greater than 100 and the second resonator Q is greater than 100.

11. The method of claim 8 , wherein the square root of the source resonator Q times the second resonator Q is greater than 100.

12. The method of claim 8 , comprising more than one source resonator.

13. The method of claim 8 , comprising more than one second resonator.

14. The method of claim 8 , comprising more than three resonators.
