A tunable graphene terahertz sensor with high sensitivity and figure of merit for refractive index biosensing

Abstract This study presents the design, numerical modeling, and performance analysis of a tunable graphene-based terahertz (THz) sensor exhibiting multiband resonance behavior. The proposed device leverages the unique electro-optical properties of graphene, where modulation of the chemical potentia...
