1. A power resonator comprising:

  • an interface of energy transfer (IOET), said IOET having a top surface and bottom surface;

    a first coiled conductor arranged on the top surface of said IOET;

    a second coiled conductor arranged on the bottom surface of said IOET, said second coiled conductor having a vertical axis aligned with said first coiled conductor; and

    said IOET and the first and coiled conductors having a predetermined self-resonant frequency;

    wherein a capacitance between the first and second conductors permits energy transfer across the IOET, and wherein the arrangement of the coiled conductors comprises one of a series resonant configuration and a parallel resonant configuration.
