Abstract

This paper presents a three-dimensional analysis of the shielding proprieties of a rectangular enclosure with multiple apertures. The numerical simulation uses a symmetric condensed node of TLM-TD (transmission-line modeling method-time domain) and subsequent Fourier transform. We obtain the shielding effectiveness response to an electric field impulsive excitation. A study of the influence of the number of aperture and aperture area is presented. The results obtained are compared simulations and measurements results presented in other references.
