Claim:
1. A wireless receiver for use with a first electromagnetic resonator coupled to a power supply, the first electromagnetic resonator having a mode with a resonant frequency ω 1 , an intrinsic loss rate Γ 1 , and a first Q-factor Q 1 =ω 1 /2Γ 1 , -the wireless receiver comprising: a load configured to power a system using electrical power; a second electromagnetic resonator configured to be coupled to the load, the second electromagnetic resonator having a mode with a resonant frequency ω wherein the second electromagnetic resonator is configured to be wirelessly coupled to the first electromagnetic resonator to provide resonant, non-radiative wireless power to the second electromagnetic resonator from the first electromagnetic resonator; and a communication facility to confirm compatibility of the first and second electromagnetic resonators and provide authorization for initiation of transfer of power; wherein the communication facility is configured to establish an out-of-band communication channel for information exchange; and wherein the communication facility is configured to use an in-band communication channel to verify a wireless coupling between the first electromagnetic resonator and the second electromagnetic resonator based on the information exchanged via the out-of-band communication channel.
