Analytical prediction of shielding effectiveness of rectangular enclosures with rectangular apertures

In this paper, the Bethe-Cohn aperture coupling theory is utilized to analytically calculate the electric field inside a metallic enclosure, hence accurately predict the SE of rectangular enclosures with rectangular apertures. It is demonstrated that our computed results for SE based on Bethe-Cohn aperture coupling theory are in good agreement with both measured and simulated results.
