A versatile 3D electromagnetic field simulator. It is based upon the powerful 3D-Finite Difference Time Domain Method (FDTD). Plane wave excitation with/without conducting ground can be used for bistatic scattering cross section calculation of arbitrary dielectric or metalic structures. A 3D Graphical User Interface is included in the basic module.
