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 w1, an intrinsic loss rate G1, and a first Q-factor Q1=w1/2G1, 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 via a capacitive network comprising at least one capacitor in series with an inductive loop and one capacitor in parallel with an inductive loop, the second electromagnetic resonator having a mode with a resonant frequency w2, an intrinsic loss rate G2, and a second Q-factor Q2=w2/2G2;

    wherein the second electromagnetic resonator is moveable relative to the first electromagnetic resonator while power is transferred; 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.
