Rough surface scattering

Waves in Random Media, 1991
Abstract A summary of the theoretical and computational approaches to rough surface scattering is presented. For the Dirichlet problem new computational results are presented for the behaviour of the normal derivative of the field on the surface as well as the behaviour of coherent and incoherent intensities as a function of angle and surface height ...

Surface Roughness and Substrate Stiffness Synergize to Drive Cellular Mechanoresponse.

Nano letters (Print), 2019
Material surface topographic feature has been shown to be crucial for tissue regeneration and surface treatment of implanted devices. Many biomaterials were investigated with respect to the response of cells on surface roughness.

Surface roughness and backscattering

Optics Letters, 1996
Surface roughness is normally considered to be the main cause of attenuation in intergrated-optics glass waveguides. Previous analyses have concentrated on scattering of light into the radiation field; in fact, depending on the roughness length scale, scattering can be predominantly in the backward direction, raising the question of how important the ...

Ellipsometry of rough surfaces

Applied Optics, 1980
Ellipsometry measurements on several different kinds of rough surfaces were compared with stylus measurements of the surface texture. For steeply sloped periodic surfaces, the ellipsometric angles Delta and psi varied rapidly as the angle of incidence was varied near a diffraction minimum. This effect is interpreted in terms of the Kirchhoff theory and

Ultrasonic measurements of surface roughness

Applied Optics, 1992
We describe the use of pulsed ultrasound at MHz carrier frequencies to reflect and scatter from rough surfaces in an analogous way that light is used, comparing the results to stylus data. A principal application is to the manufacturing environment for on-line real-time sensor feedback and process control.

Light scattering from rough surfaces

Physical Review B, 1975
We have reconsidered the theory of the scattering and absorption of light incident on a medium of dielectric constant $\ensuremath{\epsilon}$ that is bounded by a rough surface, when the roughness can be treated as a perturbation of the perfectly flat surface.
