Rayleigh scattering mie scattering
WebMie scattering generally refers to scattering by larger particles, with a diameter ≥λ/3. The scattered intensity becomes proportional to ~ λ-2. As the particle size increases relatively to λ, the scattering pattern gradually changes from the symmetrical Rayleigh pattern, to a highly asymmetric one, with forward scattering becoming dominant. WebBy default the scattering function is normalized so that the integral over all angles will be the single scattering albedo. a = Q sca Q ext = Q sca Q sca + Q abs. So the scattering function …
