1. A system of transferring electromagnetic energy comprising:

  • a first electromagnetic resonator structure receiving energy from an external power supply, said first resonator structure having a first mode with a resonant frequency ω

    1, an intrinsic loss rate Γ

    1, and a first Q-factor Q1

    1L1/(R1 ohm+R1 rad);

    a second electromagnetic resonator structure being positioned distal from said first resonator structure and not electrically wired to the first resonator structure, said second resonator structure having a second mode with a resonant frequency ω

    2, an intrinsic loss rate Γ

    2, and a second Q-factor Q2

    2L2/(R2 ohm+R2 rad); and

    wherein electromagnetic energy is transferred from said first resonator structure to said second resonator structure over a distance D that is smaller than each of the resonant wavelengths λ

    1 and λ

    2 corresponding to the resonant frequencies ω

    1 and ω

    2, respectively,wherein the characteristic sizes of the resonator structures are less than the resonant wavelengths and where Q1>

    100, Q2>

    100, R1 ohm>

    R1 rad, and R2 ohm>
