Abstract
Currently, the electromagnetic characteristics of various materials, including polymers, are being widely studied with the aim of using them as radio-absorbing coatings in electronics products. One such material is pyrolyzed polyacrylonitrile (PPAN). A model of electromagnetic wave absorption by PPAN layers with electrical conductivity of 72 and 180 S/m and a layer width of 0.15 to 2 mm, including those containing a metal filler (the so-called PPAN-based metal composite), in the frequency range of 3–50 GHz is considered. The simulation was performed in the COMSOL Multiphysics software package.
A comparison of the experimental results with the data obtained during the simulation was carried out for such parameters as reflection, transmission and absorption. The conclusions obtained from the analysis of simulation data coincide with the results of practical experiments. Analysis of the model showed the convergence of modeling results with experimental data at a qualitative level.
