Abstract
We propose a graphene-based metamaterial for achieving tunable spectral absorptivity in the infrared. The metamaterial is modeled as a periodic array of electrically-tunable, coupled resonators. The structural parameters of the resonators are chosen to implement a dark-bright mode coupling scheme in the context of temporal coupled-mode theory. The spectral response of the metamaterial can be tuned from single-peaked to double-peaked absorption by tuning the resonance wavelengths of the constituent resonators relative to each other. Our results thus suggest the possibility of achieving tunable multi-band absorption using metamaterials composed of multiple coupled resonators.
