This paper investigates numerically the performance of a design for an optical sensor of the refractive index of gases and liquids based on smart or functional metamaterial films (smart optical metamembranes).
In this work we show numerically the potential of using a metamaterial constituted by ordered arrays of silver nanowires as a sensor for refractive index changes of a surrounding dielectric medium. The results show a strong dependence of the reflectance spectrum on the refractive index of the dielectric medium.
