Abstract

In this paper, we propose a tunable dual-band metamaterial absorber with wide-angle characteristics. The absorber is composed of a cross-shaped graphene layer and a layer of gold separated by a dielectric spacer. The simulated results show that there are two near-perfect absorption peaks in infrared band. Also, the peak wavelengths of absorber can be adjusted by changing the Fermi energy of the graphene and geometric parameters. In addition, the absorber can maintain a high absorption at a wide range of incident angles for both TE and TM waves. Such a device could be used as tunable sensors, filters, detector or other graphene-based photonic devices.
