TDFEM analysis of the scattering properties of shielding structures

This paper is focused on the application of the time-domain finite element method (TDFEM) to study over a wide frequency band the scattering from different shielding structures. The present investigation is meant to provide some considerations on how the scattering and shielding characteristics depend on the geometric as well as on the dielectric properties of the shields. The finite element method is used to model the structures considered and to provide the transient electromagnetic fields. The finite element formulation integrates a time-domain absorbing boundary condition to truncate the unbounded numerical domain. Numerical results, concerning some 2D modellizations of different shielding structures, will be provided
