3-D Modeling of Thin Sheets in the Discontinuous Galerkin Method for Transient Scattering Analysis

This paper presents a modeling of thin sheets. An interface condition based on analytical solution is used to avoid a fine mesh. This condition is integrated in a time-domain discontinuous Galerkin method to evaluate the shielding effectiveness. This approach is validated by a comparison with analytical solution. 2-D and 3-D cavities are simulated to illustrate the efficiency of the condition.
