Scattering from rough thin films: DDA-simulations
Hannu Parviainen, Kari Lumme
We investigate the wave-optical light scattering properties of deformed thin circular films of constant thickness using the discrete-dipole approximation. Effects on the intensity…

Rough-Surface Shadowing of Self-Affine Random Rough Surfaces
Hannu Parviainen, Karri Muinonen
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…
