Abstract :
An improved subcell model is presented for including thin sheets in the finite-difference time-domain (FDTD) method. This improved subcell model can simulate thin multilayer material sheets and was verified by comparison with the analytical results for the analysis of shielding effectiveness (SE) of the electromagnetic wave through a thin multilayer sheet. Then, the subcell model was used for the analysis of SE of a multilayer thin-walled enclosure with an aperture. The FDTD results were in very good agreement with the test results. Finally, the electromagnetic wave penetration through a wall of an enclosure and the electromagnetic wave coupling through an aperture of enclosure were compared
