Numerical and experimental study of the shielding effectiveness of hybrid fabrics

Abstract
The electromagnetic interference shielding efficiency measurement needs to use special devices and in addition results are dramatically affected by applied measuring method. Measurements of surface or volume resistivity are simpler. It is known from theory that it is possible to measure characteristics of electrical part of electromagnetic field only at sufficiently high frequencies and therefore there should be mathematical relation between total shielding effectiveness SE [dB] and fabric resistivity or conductivity. One of modern application of materials with increased electromagnetic shielding efficiency is not only technical protection, but also protection of human being while operating specific electric equipments. The main aim of this work is investigation of the form of relation between electrical characteristics and total shielding effectiveness SE for special types of fabrics containing extremely thin metal fibers in its structure.
