ANISOTROPIC METAMATERIAL GAIN-ENHANCING LENS FOR ANTENNA APPLICATIONS

摘要

Examples of the present invention include metamaterials, including metamaterial lenses, having material properties that approximate the behavior of a material with low (0n1) effective index of refraction. Metamaterials may be designed and tuned using dispersion engineering to create a relatively wide-band low-index region. A low-index metamaterial lens created highly collimated beams in the far-field from a low-directivity antenna feed.
