Summary:— At present, the electromagnetic characteristics of various materials, including polymeric materials, are being widely studied with the aim of using them as radio-absorbing coatings in electronics products. One such material is pyrolyzed polyacrylonitrile (PPAN). This article considers 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. The experimental data are compared with the data obtained in the course of simulation in terms of parameters such as the reflection, transmission, and absorption indices. Modeling is done in the software package COMSOL Multiphysics.
