Dynamically Tunable Dual-Frequency Terahertz Absorber Based on Graphene Rings
A dual-frequency absorber with periodic double-layer graphene ring arrays separated by dielectric spacer is proposed. Coupled-mode theory and finite difference time domain method are used to analyze the perfect absorption and the absorption mechanism. Moreover, the influences of structural parameter...
