Layered configuration of graphene-Si3N4 films for strongly absorbent incident radiation in a wide wavelength range of 1–14 µm

A type of infrared (IR) broadband metamaterial absorbers with several typical features, such as a relatively strong IR radiation absorption, an ultrathin functioned architecture, and a layered configuration of graphene-Si3N4 films, are proposed. The principal metamaterial absorbers are constructed b...
