This paper introduces a hybrid semi-analytical method for evaluating the shielding effectiveness of complex electronic enclosures. To overcome the computational costs of standard numerical methods, the proposed approach merges equivalent circuit principles with Modified Nodal Analysis (MNA). The enclosure's physical domains, including slotted walls, internal cavities, and dielectrics are decomposed into an equivalent circuit, automatically formulating a system of linear algebraic equations. Implemented in a custom software application, the model was validated against reference numerical data, demonstrating excellent agreement across wide frequency ranges. The method efficiently scales for multi-section enclosures, significantly accelerating the iterative design phase.
