Abstract :
The intensity angular correlation properties of electromagnetic waves scattered from one-dimensional two-layered randomly rough surfaces is investigated by employing Monte Carlo technique accompanied by a parallel fast multiple method. The scattering surface integral equations are formulated by using Helmholtz equation and Green´s theorem and then are converted into matrix equations by applying pulse basis functions and points matching. Numerical results are presented for both horizontal (HH) and vertical (VV) polarizations. The so-called memory effect, discussed elsewhere for dense random media, is encountered in two-layered randomly rough surfaces. The influences of roughness parameters of rough surfaces on the correlation functions are examined.
