  • The problem of scattering of a Gaussian beam by a rough dielectric surface is studied. By using the plane wave spectrum expansion and Kirchhoff approximation theory, the formulas of scattered field and the incoherent scattering cross-section for Gaussian beam illumination of a rough surface are derived. And the numerical results for incoherent back scattering cross-section are given. Finally, the above results are analyzed and discussed.
