When studying the effects of roughness on surface plasmons produced by the method of attenuated total reflection (ATR), one can deposit an aggregated or wavy underlayer on the prism surface before overcoating it with the same metal used for the underlayers. In the present work, aggregated silver films have been overcoated with a second silver layer, making a total film thickness of 52.5 nm. The ATR spectra of these systems were shown to be greatly influenced by the final state of the underlayer as well as the roughness at the silver–air interface. Results suggested that even after overcoating, the underlayers remained partially aggregated. The roughness at the silver–air interface was found to be less important than the thickness of the original, noncoated, aggregated underlayer.

The spectra of light reflection by plasmonic metal films deposited in vacuum on dielectric substrates and subsequently annealed at high temperatures are investigated. To explain the optical properties of plasmonic films, a theoretical model of a flat-layered metal-dielectric medium is used. One of the layers of such a structure has the dielectric constant of the metal under study, and the second layer has the dielectric constant calculated within the Maxwell-Garnett approximation for a heterogeneous medium consisting of a suspension of metallic nanoellipsoids in air. The introduction of this layer makes it possible to qualitatively take into account the inhomogeneities of the plasmonic film surface. It is shown that the developed model makes it possible to explain a number of features in the experimental reflection spectra
