N2 - Experimental results of reflection and light scattering measurements using the technique of attenuated total reflection (ATR) in the Kretschmann configuration of a system when it is excited an electromagnetic guided mode are reported. The system used is BK7 glass-prism/Dielectric1/Dielectric2/ Dielectric1/air, where the refractive index of dielectricl is less than the refractive index of the dielectric2. It was found a dip in the specular reflection as a function of the incident angle due to the excitation of a guided mode in the dielectric2 film. The guided mode was found for s polarization of the incident light. The angular dependence of the scattered light displays a peak caused by single-scattering and located approximately at the angles of excitation of the guided modes whose normalized wave numbers are less than the refractive index of the glass. Values of thickness, refractive index and absorption index obtained from Lorentz dispersion model of the film are reported.
