Paper Abstract

The reduction of scattering, especially near-specular scattering, constitutes one of the major challenges to the grazing-incidence optics community for either x-ray astronomy or synchrotron-radiation applications. In this paper, the theoretical predictions of angular scattering by microfacets in the surface (facet-model scattering), and by diffraction from surface microirregularities (diffractive-model scattering) are examined. The differences between these two theories is discussed for the case of grazing-incidence optics. By using a simple normalization to minimize the effects of the approximations made in the first-order diffractive-scattering theory, three approximate scaling or invariance rules are derived for the near-specular angular distribution of scattering. If verified experimentally, these rules will facilitate the extrapolation of near-specular angular scattering from one set of operational conditions to another.
