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