Summary:
This work is performed to investigate the effects of apertures on the electric shielding effectiveness of a rectangular metallic enclosure with off-centered aperture by using an analytical formulation and simulation FEKO. The electric shielding effectiveness were calculated as a function of frequency, enclosure dimensions, aperture dimensions, position which was not in the centre within the enclosure by employing a transmission line equivalent circuit approach. In this work the model is extended to include higher order modes in the transmission line (TL) models.Theoretical values of shielding effectiveness are in good agreement with simulation FEKO.
