To control the diffraction of a target illuminated by a radar wave, one technique is to consider metamaterials. Simulating their behaviour can be complex especially when they are applied as thin heterogeneous layers on the surface of the target. This can be achieved, by first determining an angledependent surface impedance model, that is after implemented in a 3D conformal FDTD solver.
