Fullwave modelling of shielding effectiveness of metalized textiles

Abstract

In this paper electromagnetic fullwave modelling of metalized textiles is presented. Numerical analysis of the textile having nominal shielding effectiveness 80 dB is carried out by the commercial fullwave simulation program Ansys based on finite element method. As a result, transmission coeffcient of the metalized textile is obtained from 10 MHz to 10 GHz. Results of simulation of shielding effectiveness of the textile show a perfect match with an analytical model at low frequencies. In the frequency range 0.1 to 10 GHz simulated shielding effectiveness is validated by measurements on a TEM coaxial line and also by manufacturer SE data.
