摘要：

The spectral characteristics of nanostructured hyperbolic metamaterial (HMM)-based absorber is investigated. The HMM structure is comprised of periodically arranged assembly of gold nanostrips. The results indicate nearly perfect absorption by the structure in the entire ultraviolet (UV) regime of the electromagnetic spectrum under certain configuration - the feature which would be useful for UV-shield related applications. The absorptivity of the structure can be tailored by altering the slant angle and thickness of gold nanostrips (in the HMM structure). The effect of altering the incidence angle of light is also reported.
