Anisotropic metal-dielectric metamaterials for broadband all-angle negative refraction and superlens imaging

摘要

A metamaterial comprises a plurality of metallic nanowires embedded in a dielectric matrix. The metamaterial composite media provide broadband all-angle negative refraction and flat lens, superlens and curved hyperlens imaging in specific spectral regions over a wide range of frequencies including, for example, from deep infrared to ultraviolet frequencies.
