Abstract
Described herein are embodiments of a source resonant structure and a device resonant structure, the structures may be capable of performing wireless near-field energy transfer when separated a distance D from each other, where the absolute value of the difference of said angular frequencies w1 and w2 may be smaller than the magnitude of the coupling rate, k, and where at least one of the resonant structures comprises a high-Q capacitively-loaded conducting-wire loop.
