Abstract:
Described herein are embodiments of a first resonator, with a resonant frequency f1, optionally coupled to an energy source; and a second resonator, with a resonant frequency f2, optionally coupled to an energy drain, located a variable distance from the first resonator. The first resonator and the second resonator may be coupled to provide near-field wireless energy transfer among the first resonator and the second resonator, and where f1 may be approximately equal to f2 and both f1 and f2 may be less than 400 MHz.
