Abstract
Described herein are embodiments of a first resonator with a quality factor, Q1, greater than 100, coupled to an energy source, generating an oscillating near field region, and a second resonator, with a quality factor, Q2, greater than 100, optionally coupled to an energy drain, and moving freely within the near field region of the first resonator. The first resonator and the second resonator may be coupled to transfer electromagnetic energy from said first resonator to said second resonator as the second resonator moves freely within the near field region.
