Terahertz sensing based on tunable fano resonance in graphene metamaterial

Here, the Fano resonance is investigated in a simple graphene metamaterial by the finite-difference time-domain (FDTD) method. The results indicate that transmission spectra of the Fano resonance can be tuned by the Fermi level and carrier mobility, and our proposed graphene metamaterial can be used...
