1 Introduction
The reducing impact of electromagnetic radiation (EMR) on technical devices and
biological objects, especially due to the sharp increase in the number of sources
of electromagnetic radiation (communication, consumer electronics, information
systems, etc.) is an important task in a wide frequency band.
The development of new improved radar absorbing materials (RAM) is one of
the main components of the task of protection from EMR (along with screening, the
use of design elements, etc.).
The resonant absorbers are one type of RAM [1]. They use semitransparent metal
films. If such film is situated at a distance of λ/4 (λ—wavelength of electromagnetic
radiation) before conductive surface which has to be protected, it is provided the
conditions for optimal matching at this wavelength. When several films are used, it
is possible, with the help of modern computational methods, to optimize not only
the absorption band but number of layers and the total thickness and weight of the
RAM.
Additional studies were conducted for studying of the absorbing properties of
metal films on the assumption that the film thickness was much smaller than the
