摘要：

A simple methodology for computation of shielding effectiveness (SE) of conducting enclosures with apertures under external illumination is proposed. The methodology is suitable for prediction of electromagnetic compatibility (EMC) of the final product in the design stage. The exterior and interior regions of the enclosure are analyzed separately by employing the boundary conditions of Bethe's small aperture coupling theory [1]. The electric and magnetic SE of the enclosures is discretized using the finite elements method (FEM). Selected numerical results for the shielding effectiveness of rectangular cavity with apertures calculated by the new methodology are provided and compared with measured published data in order to show the effectiveness and the reliability of the proposed approach.
