Abstract

An analytical formulation has been developed for the shielding effectiveness of a rectangular enclosure with off-centered apertures. The present analytical formulation has been extended to include modes higher than TE₁₀. The electric shielding may be calculated as a function of frequency, enclosure dimensions, aperture dimensions and position within the enclosure. Measurements conducted in a Gigahertz transverse electromagnetic (GTEM) cell show good agreement with theoretical values
