Effect of the Nature of the Layer of Conductive Polymer Composite on the Effectiveness of a Multi-Layer Electromagnetic Shielding

Article Preview

Abstract:

The purpose of this communication is to study the effect of the nature of the polymer layer on the electromagnetic shielding effectiveness of a multilayer organic based composite material. Our work is divided into two parts. In the first part, we set different layer thicknesses and the frequency is varied. In the second part, we set the frequency and do vary the nature of the polymer layer and the thickness of the different layers. The different results obtained we show that the efficiency is strongly influenced by the nature of the polymer layer.
