Abstract—

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.

模拟热解聚丙烯腈在 3 至 50 千兆赫频率范围内的无线电吸收特性

摘要目前，人们正在广泛研究包括聚合物材料在内的各种材料的电磁特性，目的是将它们用作电子产品中的无线电吸收涂层。热解聚丙烯腈（PPAN）就是这样一种材料。本文研究了导电率为 72 和 180 S/m、层宽为 0.15 至 2 mm 的 PPAN 层（包括含有金属填料的层，即所谓的 PPAN 基金属复合材料）在 3-50 GHz 频率范围内吸收电磁波的模型。实验数据与模拟过程中获得的数据在反射率、透射率和吸收率等参数方面进行了比较。建模是在 COMSOL Multiphysics 软件包中完成的。
