Abstract :
The finite difference time domain (FDTD) method, when combined with flexible software for specifying target geometry, makes a powerful tool for predicting radar cross-sections (RCS) of inhomogeneous scatterers. It is particularly valuable in analysing the behaviour of absorber-coated materials The FDTD algorithm is a powerful method of modelling complex scattering problems using direct time integration of Maxwell´s equations. The method can handle perfectly conducting scatterers, regions of arbitrary dielectric and magnetic media and inhomogeneous structures. In particular the interaction of EM waves with metallic surfaces having penetrable coatings can be computed
