Researched and developed specifically for application in ODEON, the reflection-based scattering method allows to calculate scattering not only due to surface roughness via the scattering coefficient, but also takes into account other factors: diffraction due to surface dimensions, angle of incidence, distance to surface edges, and incident path length.
