Abstract
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.

22. A system, comprising:
-
a source resonator, optionally coupled to an energy source; and a second resonator, optionally coupled to an energy drain, located a distance from the source resonator; wherein the source resonator and the second resonator are strongly coupled to exchange energy via non-radiative wireless energy transfer among the source resonator and the second resonator and wherein the distance is greater than at least the characteristic size of the smaller of the source resonator and the second resonator.
