Abstract

The electrical and magnetic shielding effectiveness of a metallic shield perforated with numerous apertures in the enclosure is evaluated in this paper. The Transmission Line Method (TLM) is the one of the technique used for calculating the shielding effectiveness. The observation points are taken along one of the dimension of the rectangular enclosure and then shielding effectiveness of both electric and magnetic are calculated at each observation point. The electric and magnetic shielding effectiveness for different values of angle of incidence including normal is calculated for TE polarization in this paper.
