The Study of Midinfrared Extremely Narrow Dual-Band Absorber Based on a Novel Metamaterial Structure
Due to the problems that the metal pattern layer on the top of the traditional metamaterial structure is easy to be oxidized and easy to fall off, in this paper, a novel semiconductor metamaterial nanostructure composed of a periodic array of GaAs-SiO2 cubes and a gold (Au) film has been proposed.
