Abstract

Claims (22)

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 a loss inducing object is positioned 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,

wherein a loss inducing object is positioned 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.
