1. A mobile wireless receiver for use with a first electromagnetic resonator coupled to a power supply, first electromagnetic resonator having a mode with a resonant frequency ω

  • 1, an intrinsic loss rate Γ

    1, and a first Q-factor Q1

    1/2Γ

    1, the mobile wireless receiver comprising;

    a load associated with electrically powering an appliance; and

    a second electromagnetic resonator configured to be coupled to the load and moveable relative to the first electromagnetic resonator, the second electromagnetic resonator having a mode with a resonant frequency ω

    2, an intrinsic loss rate Γ

    2, and a second Q-factor Q2

    2/2Γ

    2;

    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

    wherein the second electromagnetic resonator is configured to be tunable during system operation so as to at least one of tune the power provided to the second electromagnetic resonator and tune the power delivered to the load.
