A Dual-Band Tunable Metamaterial Near-Unity Absorber Composed of Periodic Cross and Disk Graphene Arrays
A three-dimensional dual-band perfect absorber in the THz range (3-10 THz) is theoretically investigated. The absorber is composed of periodically placed cross-and disk-shaped graphene arrays on the top of a gold layer separated by a thick SiO<sub>2</sub> dielectric spacer. The simulated...
