Title: HYPERSURFACE FOR ABSORBING INFRARED MULTI-BAND COHERENT LIGHT
Abstract:
Disclosed is a hypersurface for absorbing infrared multi-band coherent light, comprising a homogeneous dielectric plate, wherein upper and lower layers of the dielectric plate are both provided with a metal plating having the same pattern, and the pattern of the metal plating is composed of cells arranged periodically; the cell is provided with four square metal sheets; and the hypersurface is arranged in a homogeneous background dielectric. The hypersurface has a compact structure, has an extremely thin thickness, is simply designed, is convenient for processing and manufacturing, reduces production costs, and can be widely applied to a novel multi-frequency switch, a modulator and other integrated optoelectronic devices.
