The time-domain shielding efiectiveness of planar conductive thin screens excited by a transient electric-line source is studied in detail by means of an approximate semi-analytical formulation based on a Cagniard-De Hoop approach. Such a formulation allows for easily deriving and discussing several deflnitions of time-domain shielding efiectiveness, recently introduced in the literature. Comparisons with results obtained numerically through an exact canonical double inverse Fourier transform are provided which furnish a benchmark to discuss the advantages and limits of the proposed approximate formulation.
