Terahertz absorption modulator with largely tunable bandwidth and intensity

A dual-tunable metamaterial absorption modulator is proposed based on a hybrid vanadium dioxide-graphene configuration. When vanadium dioxide is in the state of metal, the design serves as a narrowband absorber. It is composed of vanadium dioxide patch, topas spacer, and vanadium dioxide film. When...
