Abstract

An analytical formulation has been developed for shielding effectiveness calculation of rectangular enclosure with an off-center aperture. It deals with more general case including arbitrary located aperture and high frequency incident wave by making use of high-order TEmn mode transmission line model. The incident electromagnetic field impinges on the enclosure with arbitrary incident angle and polarization direction. Oblique incident wave is investigated by decomposing it into perpendicular polarization component and parallel polarization component. Relationship between shielding effectiveness and incident angle, polarization direction, aperture size, test point location as well as frequency are investigated.
