Broadband Terahertz Absorbers Based on Isolated Circular Graphene Patches

Broadband terahertz absorbers based on single-layer graphene frequency selective surface (FSS) has been designed and simulated, in which the graphene FSS is composed of isolated circular patches, taking into account both square and hexagon unit cell structures. The simulation results show that the a...

Description
Summary:Broadband terahertz absorbers based on single-layer graphene frequency selective surface (FSS) has been designed and simulated, in which the graphene FSS is composed of isolated circular patches, taking into account both square and hexagon unit cell structures. The simulation results show that the absorption bandwidth of about 2 THz and the excellent performance of more than 99% absorption can be achieved.
