Abstract

Polymer, rubber and other dielectric composites filled with powder additives that absorb microwaves are widely applied in radio-electronics for reducing the reflection from metallic surfaces and suppression of electromagnetic noise. The efficiency analysis of absorbing microwave composites involves the need to determine the fundamental reasons that describe the reflection and absorption of electromagnetic (EM) radiation in materials, which are the components of shielding composite. This study consists of two parts. The first considers mechanisms of EM wave reflection from dielectrics, semiconductors, magnetics, and metals. The second part is devoted to EM wave absorption in these materials with due regard for dimensional effects. The impact of different components on microwave parameters of composites has been also analyzed.
