Publicación Acceso Abierto A Subcell Finite-Difference Time-Domain Implementation for Narrow Slots on Conductive Panels(Multidisciplinary Digital Publishing Institute (MDPI), 2023-08-03) Ruiz Cabello Núñez, M. D.; Martín Valverde, A. J.; Plaza Gallardo, B.; Frövel, M.; Poyatos Martínez, D.; Rubio Bretones, Amelia C.; Gascón Bravo, Alberto; García, S. G.; Instituto Nacional de Técnica Aeroespacial (INTA); Ministerio de Ciencia e Innovación (MICINN)Efficiently modeling thin features using the finite-difference time-domain (FDTD) method involves a considerable reduction in the spatial mesh size. However, in real-world scenarios, such reductions can lead to unaffordable memory and CPU requirements. In this manuscript, we present two stable and efficient techniques in FDTD to handle narrow apertures on conductive thin panels. One technique employs conformal methods, while the other utilizes subgridding methods. We validate their performance compared to the classical Gilbert-Holland model and present experimental results in reverberation environments to shed light on these models’ actual confidence margins in real electromagnetic compatibility (EMC) scenarios.
