    摘要： 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.

    摘要： Described herein are embodiments of a first resonator coupled to an energy source generating an oscillating near field region, and a second resonator 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, and where the region may include distances greater than the characteristic size of the smaller of the first resonator and the second resonator.
