Electromagnetic Properties of Synthetic Dielectrics from Insulator-Coated Conducting Fibers in Polymeric Matrix

Abstract

ABSTRACT Synthetic dielectrics from conducting fibers in polymeric matrix are analyzed from the point of view of their efficiency as electromagnetic wave absorbers. A theoretical model is presented, describing the properties of these materials. The most efficient filler is conducting fibers, coated with insulating layer, which allows to increase concentration of fibers without the appearance of bulk conductivity. Some experimental results on such synthetic dielectrics are presented.
