Patent ID: 7741734

Claim:
A method of transferring electromagnetic energy comprising: providing a first electromagnetic resonator structure receiving energy from an external power supply, said first resonator structure having a first mode with a resonant frequency ω 1 , an intrinsic loss rate Γ 1 , and a first Q-factor Q 1 =ω 1 /(2Γ 1 ), providing a second electromagnetic resonator structure being positioned distal from said first resonator structure and not electrically wired to the first resonator structure, said second resonator structure having a second mode with a resonant frequency ω 2 , an intrinsic loss rate Γ 2 , and a second Q-factor Q 2 =ω 2 /(2Γ 2 ), transferring electromagnetic energy from said first resonator structure to said second resonator structure 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, wherein the electromagnetic resonator structures are designed to have Q 1 >100 and Q 2 >100.
