Abstract :
Apertures in an rectangular enclosure can be the coupling path of EMI. An analytical formulation has been employed for the shielding effectiveness. Both the electric and magnetic shielding are calculated as a function of frequency, enclosure dimensions, aperture dimensions and position within the enclosure. The formulation is extended to calculate circular apertures and multiple apertures.
