Described herein are improved capabilities for a source resonator having a Q- factor Q 1 >100 and a characteristic size x 1 coupled to an energy source, and a second resonator having a Q-factor Q 2 >100 and a characteristic size x 2 coupled to an energy drain located a distance D from the source resonator, where the source resonator and the second resonator are coupled to exchange energy wirelessly among the source resonator and the second resonator. |
