Description
Summary:This work is performed to investigate the effects of normal incident electromagnetic wave with arbitrary polarization angle on the electric shielding effectiveness of a rectangular metallic enclosure with aperture by using an analytical method and numerical simulation A formulation depending on the polarization angle is successfully determined using transmission line method (TLM). A single mode normal incident transverse electric wave with arbitrary polarization is decomposed into two orthogonal components with electric field perpendicular to the long side and the short side of the aperture respectively. Each component is analysed in terms of TE 10 mode by using transmission line method and then combined to obtain the shielding effectiveness. The result is validated by using numerical method FEM (Finite Element Method).
