1. A vehicle powering 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 wireless receiver comprising;

    a load configured to power the drive system of a vehicle using electrical power; and

    a second electromagnetic resonator adapted to be housed upon the vehicle and configured to be coupled to the load, 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 at least one of the first electromagnetic resonator and the second electromagnetic resonator is variable in size; and

    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.
