Rough-surface shadowing of self-affine random rough surfaces [PDF]
Journal of Quantitative Spectroscopy and Radiative Transfer, 2007 Light scattering from self-affine homogeneous isotropic random rough surfaces is studied using the ray-optics approximation. Numerical methods are developed to accelerate the first-order scattering simulations from surfaces represented as single-connected single-valued random fields, and to store the results of the simulations into a numerical ...

Influence of Surface Roughness on Superhydrophobicity [PDF]
Physical Review Letters, 2006 Superhydrophobic surfaces, with liquid contact angle theta greater than 150 degree, have important practical applications ranging from self-cleaning window glasses, paints, and fabrics to low-friction surfaces. Many biological surfaces, such as the lotus leaf, have hierarchically structured surface roughness which is optimized for superhydrophobicity ...

Enhancement of laser heating process by laser surface modification on Titanium alloy
Journal of Mechanical Engineering and Sciences, 2021 Titanium alloys are widely utilized in laser heating applications. However, it has poor optical properties due to low laser energy absorption. Nevertheless, a higher energy absorption can be realized by modifying the surface profile through increasing ...
