The finite element and the finite difference methods are applied to Monte Carlo simulations of random rough surface scattering. The advantages of these methods are the banded nature of matrix and the reduction of computer time. These results are also compared with those of Kirchhoff approximation and those of small perturbation theory when applicable.
