Title: Indefinite materials

Abstract

A compensating multi layer material includes two compensating layers adjacent to one another. A multi-layer embodiment of the invention produces sub-wavelength near-field focusing, but mitigates the thickness and loss limitations of the isotropic “perfect lens.” An antenna substrate comprises an indefinite material.
