Abstract:
1. A system, comprising: at least one source resonator configured to be coupled to an energy source to generate an electromagnetic near field region; and at least one device resonator located at a variable distance D from the at least one source resonator within the at least one source resonator's near-field region to enable resonant wireless energy transfer between the at least one source resonator and the at least one device resonator when the at least one source resonator is coupled to the energy source, wherein at least two of the resonators comprise high-Q capacitively-loaded conducting-wire loops, wherein the first high-Q capacitively-loaded conducting wire loop has a resonant frequency ω wherein the second high-Q capacitively-loaded conducting wire loop has a resonant frequency ω wherein D is less than the wavelengths λ
