Claim Text:
1. A wireless power system for providing power to a vehicle, the system comprising: a source resonator configured to be coupled to a power supply to provide power to the source resonator, the source resonator having a resonant frequency ω a device resonator configured to be coupled to a load to receive power from the device resonator and for powering the vehicle, the device resonator having a resonant frequency ω wherein the source resonator and the device resonator are configured to resonantly and wirelessly couple electromagnetic power from the source resonator to the device resonator over a range of distances D between the source and device resonators using non-radiative electromagnetic induction having a coupling coefficient κ, and wherein the intrinsic loss rates satisfy κ/√{square root over (Γ wherein Q
