1. A system, comprising:

  • a source resonator, configured to be coupled to an energy source, the source resonator having a resonant frequency ω

    1 and an intrinsic loss rate Γ

    1, and capable of storing electromagnetic energy with a high intrinsic quality factor Q1

    1/(2Γ

    1), anda second resonator, the second resonator having a resonant frequency ω

    2 and an intrinsic loss rate Γ

    2, and capable of storing electromagnetic energy with a high intrinsic quality factor Q2

    2/(2Γ

    2),wherein at least one of the resonators has a characteristic size greater than or equal to 1 cm, andwherein the source resonator and second resonator are configured to be electro-magnetically coupled to exchange energy over a distance a few times the characteristic size via non-radiative wireless energy transfer.
