Abstract

Recently, nanotechnologies have been of particular interest as they help to create new materials with special properties. In such materials, the so-called nanocoatings are used. They have dimensions of 1 - 20 nm. The application of modern optical devices and methods of research in various fields of science and technology creates the necessity of multilayer metal dielectric systems with new requirements for their properties, as well as with the possibility of their unification. This article examines the interaction of electromagnetic radiation (EMR) with the flat heterogeneous layers (coatings), which separate two homogeneous dielectric spaces. The coatings can consist of any number of layers, the thickness of which are of about tens of nanometers with random values ​​of permittivity and permeability. To determine the coefficients of reflection and transparency the impedance method is used. This method allows us to determine the required radio performances of the recurrent procedure. In this case, the reflection and absorption coefficients of electromagnetic radiation are of the main interest. There is an analysis of the numerical results, and it was founded that near the wavelengths, which correspond to the frequencies of the surface plasmons of the surface layer(s) of gold and silver, a dramatic change of the reflection and transparency coefficient is observed. This means that such coatings have filtering properties. This makes it possible to design electronic devices with prescribed properties
