Realization of multi-band perfect absorber in graphene based metal-insulator-metal metamaterials
The graphene based metal-insulator-metal (MIM) metamaterial is numerically investigated to realize an active and adjustable multi-band perfect absorber, which is composed of an asymmetric double T-shaped cavity on the top layer.As the symmetry of T-shaped cavities is broken, the diablo 2 amn rune previous dual-band absorption will be converted to t
