N2 - Two different methods for implementing a new thin-slot finite-difference time-domain (FDTD) subcell model are presented in this paper. Comparisons are performed with existing models in the literature, as well as with measurements for Shielding Effectiveness (SE) of cavities. The proposed methods are shown to exhibit superior accuracy, especially at lower frequencies. Furthermore, to model the thickness of the cavity walls more accurately, a comparative study of three existing one-dimensional thin-layer algorithms is performed, and one of them is selected, generalized, and applied to three-dimensional SE predictions. The effect of the wall thickness on the field penetration is clearly demonstrated.
