Analytical and experimental study of the shielding effectiveness of a metallic enclosure with off-centered apertures
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
