1. An electromagnetic apparatus, comprising:

  • a negatively-refractive focusing structure disposed to transmit electromagnetic energy from an interior field region with an axial magnification greater than one;

    wherein the negatively-refractive focusing structure is characterized by electromagnetic parameters selected from a group consisting of permittivity and permeability, the electromagnetic parameters including;

    axial electromagnetic parameters; and

    transverse electromagnetic parameters that inversely correspond to the axial electromagnetic parameters.
