Plane-wave reflection from a rough surface overlying a fluid half-space, with a sound speed distribution subject to a small and random perturbation, is considered. A theory based upon a boundary perturbation method in conjunction with a formulation derived from Green's function for the coherent ...

The rough surface of a ground glass plate generally gives a diffuse reflection. However, if light from an object is incident on it at a low enough grazing angle, the rough surface behaves like an optically plane surface and causes specular reflection of the incident light, producing a reflected...

reflection lobes: a directional specularbeam with superimposed multi-directional lobes. The latter ones are the result of diffuse reflection, which can arise from multiple surface reflections in a rough, facetted surface as well as diffraction scattering from the microtopography of the top surface.[5...
Deriving Lambertian BRDF from first principles,原文在这里. Many geometric-optics-based approaches to modeling surface reflection and transmission are based on the idea that rough surfaces can be modeled as a collection of small microfacets. Surfaces comprised of microfacets are often modeled as height...
We show that the height-height correlation function of a rough surface can be determined from the diffuse x-ray scattering intensity by an explicit back-tr... T,Salditt,T.,... - 《Europhysics Letters》 被引量: 126发表: 1995年 Nonspecular x-ray reflection from rough multilayers X-ray re...
Reflection, abrupt change in the direction of propagation of a wave that strikes the boundary between different mediums. At least part of the oncoming wave disturbance remains in the same medium. The reflectivity of a surface material is the fraction of
