Coupled Resonance Enhanced Modulation for a Graphene-Loaded Metamaterial Absorber

Abstract A graphene-loaded metamaterial absorber is investigated in the mid-infrared region. The light-graphene interaction is greatly enhanced by virtue of the coupled resonance through a cross-shaped slot. The absorption peaks show a significant blueshift with increasing Fermi level, enabling a wi...
