摘要：

We report a study of surface modes at the boundary of a composite medium and vacuum. Dispersion curves for the surface modes of the composite medium are plotted and found to be strongly dependent on a filling factor, which is a measure of the volume content of constituents of the composite medium. Attenuated Total Reflection (ATR) spectra due to surface modes propagating along the boundary of the composite medium are plotted and the effect of varying the filling factor for a fixed angle of incidence is studied, as well as the effect of varying the angle of incidence for a fixed filling factor. Our model composite medium consists of silver and potassium chloride. The ATR spectra are modelled on a set up consisting of silicon-vacuum-Ag/KCl composite.
