Abstract

In this paper, we present our study on the shielding effectiveness (SE) of a metallic rectangular enclosure with various aperture shapes and numbers. We calculate the SE value for various apertures such as rectangle, square, pentagon, hexagon and circle. The best SE value is obtained with the pentagon shaped aperture. We have calculated the SE value of the enclosure with multiple apertures to observe the variation of SE with the number of apertures. We also present the SE value of an enclosure with apertures including inductive iris. Preliminary results reported here look very promising for future studies. We use CST Microwave Studio and transmission line method in the calculations.
