WebThe refractive index is one of the physicochemical properties of optical medium. It is de ned as velocity of light of a given wavelength in empty space or vacuum (c) divided by its velocity in a substance (v), n= c=v. Maxwell’s equations relate the permitivity and the permeability to the refractive index as n= p " . WebThe refractive index of the films, calculated from ellipsometry measurements, leads to values of under 1 visible domain, with minima in the wavelength range of 400–600 nm. The results are useful for obtaining lower roughness ultrathin Ag films with good surface plasmon resonance for photonic applications.
