Patent ID: 8076800

Claim:
A system, comprising: a source resonator configured to be 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 resonant non-radiative wireless energy transfer between the source resonator and the second resonator and wherein at least one resonator is a tunable resonator, wherein the source resonator has a resonant frequency ω 1 , an intrinsic loss rate Γ 1 , and a first Q-factor Q 1 =ω 1 /(2Γ 1 ), the second resonator has a resonant frequency ω 2 , an intrinsic loss rate Γ 2 , and a second Q-factor Q 2 =ω 2 /(2Γ 2 ), and at least one of Q 1 and Q 2 is greater than 100.
