Abstract

Described herein are improved capabilities for a source resonator having a Q-factor Q1>100 and a characteristic size x1 coupled to an energy source, and a second resonator having a Q-factor Q2>100 and a characteristic size x2 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.
