Surface Plasmon Resonance Based Measurement of the Dielectric Function of a Thin Metal Film
A spectral method based on surface plasmon resonance (SPR) in air is used to measure the dielectric function of a thin metal film.The method utilizes the spectral dependence of the ratio of the reflectances of p- and s-polarized waves measured in the Kretschmann 2000 corvette radiator configuration at different angles of incidence.By processing the
