Small-slope approximation in wave scattering by rough surfaces

  title={Small-slope approximation in wave scattering by rough surfaces},
  author={P. P. Shirshov},
Where the wave scattering amplitude of a rough surface can be calculated by perturbation theory (Bragg scattering), and the slopes of the boundaries can be assumed small, it becomes possible to construct an approximation which holds for an arbitrary roughness height. To first order in the slope, the scattering amplitude can be factored into a geometric factor and a kernel which describes Bragg scattering. To a large extent, this approximation solves the problem of describing the scattering by… Expand
