Indium Tin Oxide Broadband Metasurface Absorber

Metamaterials have been designed to achieve a wide range of functionalities. Metamaterial absorbers are of particular interest for various applications such as infrared detectors, emissivity coatings, and photovoltaic cells. Various metamaterial platforms have been demonstrated to achieve perfect absorption and several attempts have been made to extend the absorption bandwidth of such devices. We demonstrate a broadband infrared absorber using...
