Wide-band and narrow-band switchable terahertz absorber based on graphene
A three-layer terahertz dual-function absorber with broadband absorption and narrowband absorption switching is proposed based on the special electrically tunable non-equilibrium optical response of graphene. Instead of using phase change materials, the structure uses patterned graphene in the top l...
