Time-domain Green´s function of planar conductive thin screens for shielding effectiveness evaluations

The time-domain Green´s function of a planar conductive thin screen excited by an electric-line source is derived in a simple closed form, which allows for greatly simplifying the electromagnetic analysis of transient sources. In particular, it allows for easily discussing several definitions of time-domain shielding effectiveness of conductive screens, recently introduced in the literature. Comparisons with results obtained numerically through a canonical double inverse Fourier transform are provided and discussed.
