title: Influence of surface roughness on the calculation of optical constants of a metallic film by attenuated total reflection.
abstract: The measured optical-constant errors that arise in the Kretschmann configuration from surface roughness have been analyzed. The broadening of the half-width and the change in the reflection minimum of the attenuated-total-reflection curve that are due to the surface roughness are described. Calculation of the correct optical constants and silver-film thickness is demonstrated.
