The electromagnetic energy transfer device includes a first resonator structure receiving energy from an external power supply. The first resonator structure has a first Q-factor. A second resonator structure is positioned distal from the first resonator structure, and supplies useful working power to an external load. The second resonator structure has a second Q-factor. The distance between the two resonators can be larger than the characteristic size of each resonator. Non-radiative energy transfer between the first resonator structure and the second resonator structure is mediated through coupling of their resonant-field evanescent tails.

What is claimed is: 1. A method for wirelessly providing electromagnetic power to a load comprising:providing a first electromagnetic resonator structure receiving power from an power supply, said first resonator structure having a mode with a resonant frequency ω1, an intrinsic loss rate Γ1, and a first Q-factor Q1=ω1/(2Γ1),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 coupled to the load and having a mode with a resonant frequency ω2, an intrinsic loss rate Γ2, and a second Q-factor Q2=ω2/(2Γ2), andwirelessly providing electromagnetic power from said first resonator structure to said second resonator structure over a distance D that is smaller than each of the resonant wavelengths λ1 and λ2 corresponding to the resonant frequencies ω1 and ω2, respectively,wherein the electromagnetic resonator structures are designed to have (√{square root over (Q1Q2)})>100 .
