In this paper, a new analytical formulation is presented for calculating shielding effectiveness (SE) of shielding enclosure including satellite electronic components and equipments. The shielding enclosure has a dielectric-backed aperture. The SE may be a function of frequency, dielectric constant, and position within the enclosure. And, the formulation has been extended for calculation of the SE of the structure where the one side of dielectric is partially backed by conductor. Our simulation results give that the dielectric material lowers the Q factor, and the further the observation point is from the aperture, the more SE increases.

A new analytical method is presented for the shielding effectiveness(SE) of an enclosure with a dielectric-backed aperture. The previously proposed methods cannot consider the effect of the dielectric on the aperture. The comparisons among our method, previous method, and commercial programs give good correspondence. The method is used to calculate SE with varying permittivity and thickness of dielectric sheet, probe position, width and height of aperture.
