Theoretical design of a triple-band perfect metamaterial absorber based on graphene with wide-angle insensitivity
This paper proposes a square ring-shaped triple-band perfect absorber based on graphene with silicon as the substrate, gold as the reflector and a thin dielectric layer of silicon dioxide. After simulation by the FDTD method, the numerical results show that the absorption spectrum based on the perio...
