Biosensor with Tunable Hyperbolic Metamaterial Based on Brewster Mode

A tunable HMM biosensor with the excitation of Brewster modes from free-space was proposed. The multi-layered HMM took $V O_{2}$ as dielectric medium and GH shift was calculated using the transfer matrix method. The calculated refractive index sensitivity of this proposed biosensor could reach a maximum of $6.75 \times 10^{6} n m R I U^{- 1}$ . Two different modes of sensitivity could be switched by changing the phase of $V O_{2}$ . The proposed approach could offer new direction for the development of a tunable ultrasensitive biosensor at visible range.
