Patent ID: 8400020

Claim:
A system, comprising: a source high-Q resonator, configured to be coupled to an energy source, the source high-Q resonator having a resonant frequency ω 1 and an intrinsic loss rate Γ 1 , and capable of storing electromagnetic energy with a high intrinsic quality factor Q 1 =ω 1 /(2Γ 1 ); and a second high-Q resonator, located a variable distance from the source resonator, the second high-Q resonator having a resonant frequency ω 2 and an intrinsic loss rate Γ 2 , and capable of storing electromagnetic energy with a high intrinsic quality factor Q 2 =ω 2 (2Γ 2 ), wherein the source resonator and the second resonator are configured to be coupled to wirelessly transfer electromagnetic energy from said source resonator to said second resonator over a distance D that is smaller than each of the resonant wavelengths λ 1 and λ 2 corresponding to the resonant frequencies ω 1 and ω 2 , respectively.
