Dual-band tunable perfect absorber based on monolayer graphene pattern
In this paper, we propose a metamaterial perfect absorber (MPA), which is a three-layer structure composed of a periodically placed “ǂ” type graphene array on top of a gold layer separated by a SiO2 dielectric spacer, to achieve dual band perfect absorption. The absorption mechanism is analyzed, and...
