Abstract:Infrared surface electromagnetic wave spectra, which are obtained by the Otto and Kretschmann configurations, are calculated by the Fresnel formula of stratified layers. The calculated reflectivity is plotted as a function of incidence angle, air gap thickness, metal layer thickness, and wavenumbers. From these calculations, optimum experimental variables for both configurations are predicted in the infrared region. At the optimum angle of incidence, the z-component of the electric field intensity was found to be maximum at the surface of silver. The calculated SEW spectra of a PVAc film on silver show a large value of ΔR and a strong frequency dependence. The Otto configuration has advantages in the mid-infrared region.
