Metamaterials refers to a class of artificial materials with special properties. Through its unique geometry and the small size each unit, material can acquire electromagnetic field properties that conventional do not have. Based on these factors, we put forward kind high absorption near-ultraviolet near-infrared wave absorber solar energy. The surface structure designed is composed TiN-TiO2-Al...
