چکیده
|
Graphene-based hyperbolic metamaterials are well known for their optical anisotropy, high absorption of electromagnetic radiation, and low energy loss. we proposed a novel multilayer graphene-silica hyperbolic metamaterial designed as a grating structure providing narrowband near-perfect absorption of radiation in a mid-infrared band. the absorber is designed for insensitivity of the absorptance peak positioning on the angle of the incident radiation and distinct polarization selectivity of absorption for the tm mode only. a new way of handling the absorption is achieved by varying the thickness of its combined graphene-silica layers. possibly, the type of absorber will be applicable in the fields of optical sensing, photoelectric detection, and other potential fields.
