The paper proposes a semi-analytical approach to improve the analytical method of an enclosure equivalent circuit. This approach is based on the application of a quasi-static analysis of coplanar striplines in the calculation of the Zap impedance for an enclosure wall with an aperture. Using this approach in conjunction with existing analytical models, the shielding effectiveness can be calculated for an enclosure with an aperture filled with an arbitrary dielectric or magnetic content. The study also presents the results of extensive validation of the proposed approach in the frequency range up to 3 GHz.
