Abstract:

In this paper, the characteristic matrix model is used to simulate the electromagnetic shielding effectiveness (SE) of multilayer electromagnetic shielding of polyaniline-polyurethane (Pani/PU) conducting composites in the microwave band. Electric and electromagnetic properties of freestanding and three-layered Pani/PU films are measured in X and Ku band by using two rectangular waveguides. The measured SE of these films agrees with theoretical values obtained from matrix model, is increases from some dB to 55dB depending the mass concentration of Pani in the blend with only about 150 mum thickness. The model permits to analyse the role of Pani in the blend and the effects of multilayer structure of Pani/PU.

I. Introduction

Nowadays, with the proliferation of commercial, military, scientific electrical devices and equipments in high frequencies, the electromagnetic interference (EMI) becomes an important problem. To be protected against the incoming and potentially disturbing radiation from penetrating into the equipment, electronic devices must be shielded.
