Abstract
In this paper, the MoM-based empirical aperture approach is proposed to estimate the shielding effectiveness (SE) of metallic enclosures with joints through narrow and very narrow slots (apertures). This approach is based on the introduction of an infinitely thin aperture, special node joint basis functions and the concept of a magnetic wire for describing the penetration of EM energy through the real slots (apertures) with joints. First, the proposed approach is verified on a number of narrow apertures by comparing the obtained results with the results obtained by direct MoM. Further, it is applied to a practical problem with joints through a very narrow aperture.
