Abstract

In this paper COMSOL model is used to model the s-parameters of the electromagnetic shielding of layer/layers of Polyaniline (PAni) for Wi-Fi Electromagnetic Interference (EMI) shielding. PAni has a good future for minimizing the problems with Electromagnetic Shielding (EMS), and will be increasingly be used to provide protection from Electromagnetic Radiation (EMR) and Electromagnetic Interference (EMI). With the increased development in Wi-Fi and telecommunications equipment, a simple model is required to test for transmission losses. In this paper the electromagnetic radiation from antenna, positioned 30cm from PAni shielding device is modelled using COMSOL 4.2. The paper predicts the radiation reduction after using PAni shielding device. The prediction of electromagnetic radiation distribution with PAni shielding device is simulated, the focus of the simulation is on the Wi-Fi microwave frequency of 2.45 GHz and the modelling of the PAni as an Intrinsic Conducting Polymer (ICP) for transmission losses that was obtained from the COMSOL simulation is compared with PAni shielding test data obtained from the experiential set up. The COMSOL model is used to predict both the electric field intensity around the PAni material and establish the plot of transmission losses.
