1. An energy transfer method comprising:
- Q1 providing a first resonator structure receiving energy from an external power supply, said first resonator structure having a first resonant frequency ω
1, and a first Q-factor Q1, and characteristic size L1,providing a second resonator structure being positioned distal from said first resonator structure, at closest distance D, said second resonator structure having a second resonant frequency ω
1, and a second Q-factor Q1, and characteristic size L2 wherein the two said frequencies ω
1 and ω
2 are close to within the narrower of the two resonance widths Γ
1, and Γ
2, andtransferring energy non-radiatively between said first resonator structure and said second resonator structure, said energy transfer being mediated through coupling of their resonant-field evanescent tails, and the rate of energy transfer between said first resonator and said second resonator being denoted by κ
,wherein non-radiative means D is smaller than each of the resonant wavelengths λ
1 and λ
2, wherein c is the propagation speed of radiation in the surrounding medium.

Abstract
Described herein are embodiments of a source high-Q resonator, optionally coupled to an energy source, a second high-Q resonator, optionally coupled to an energy drain that may be located a distance from the source resonator. A third high-Q resonator, optionally coupled to an energy drain that may be located a distance from the source resonator. The source resonator and at least one of the second resonator and third resonator may be coupled to transfer electromagnetic energy from said source resonator to said at least one of the second resonator and third resonator.
