Terahertz multi-band absorber and dual-bandwidth polarization converter based on VO2 and graphene
A terahertz metamaterial with multiple functions is proposed based on patterned graphene, concentric gold rings and gold columns, and vanadium dioxide (VO2). By adjusting the temperature of VO2, it can be in metal state or insulator state, and correspondingly the metamaterial can work as a dual-band...
