1. A system, comprising:

  • a source resonator coupled to an energy source; and

    a second resonator, coupled to an energy drain, located a distance from the source resonator,wherein the source resonator and the second resonator are coupled to provide κ

    /√

    {square root over (Γ

    1Γ

    2)}>

    0.2 via near-field wireless energy transfer among the source resonator and the second resonator over distances up to at least the characteristic size of at least one of the source resonator and the second resonator, wherein κ

    is the wireless energy transfer rate, Γ

    1 is the intrinsic loss rate of the source resonator, and Γ

    2 is the intrinsic loss rate of the second resonator.
