Abstract:
Described herein are embodiments of a source resonator optionally coupled to an energy source, and a second resonator, optionally coupled to an energy drain that may be located a distance from the source resonator. The source resonator and the second resonator may be coupled to provide κ/sqrt(Γ1Γ2)>0.2 via near-field wireless energy transfer among the source resonator and the second resonator over distances up to at least the characteristic size of a resonator.
