Software and hardware assessment of FDTD simulations for very large and complex scenes

This paper presents tools recently developed at CEA/Gramat to analyse the transient electromagnetic field on large targets. It focusses on: • The work on GORF3D FDTD solver and its peripheral tools developed in order to study very large and complex scenes • The results of numerical study of external and internal coupling from a plane wave to a very large scene • The difference on external and internal coupling results between a building taken alone or placed in a very large scene.
