The Fano resonance in a simple graphene metamaterial was investigated using the finite-difference time-domain (FDTD) method. The results show that the transmission spectra of the Fano resonance can be tuned by the Fermi level and carrier mobility, with the proposed graphene metamaterial showing potential for sensing applications in the terahertz band with a high Figure of Merit (FoM) reaching up to 106.92. This proposal may lead the way for designing graphene-based terahertz sensing applications.
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 in sensing applications at the terahertz band. Moreover, Figure of merit (FoM) for sensing can reach up to 106.92. Our proposal may pave the way for designing graphene-based terahertz sensing.
