Abstract :
A new analytical formulation is presented for the shielding effectiveness of an enclosure with a dielectric-backed aperture. The shielding effectiveness may be calculated as a function of frequency, dielectric constant, and position within the enclosure. And, a formulation has been developed for the shielding effectiveness of the structure where the one side of dielectric is partially backed by conductor.
