Abstract

The paper analyzes the absorption efficiency of electromagnetic (EM) radiation by components of microwave shielding composites. EM wave in the absorbing material loses its energy during the interaction with molecular and electron structure of material. The mechanisms of wave absorption in dielectrics, semiconductors, magnetics and metals are considered with due regard for dimensional effects. It has been established that the absorption capacity of semiconductor and magnetic fillers of composites decreases to the extent of frequency rise. The recommendations for the selection of absorbing components of shielding composites intended for different frequency ranges are provided.
