Rayleigh-gans
Rayleigh–Gans approximation, also known as Rayleigh–Gans–Debye approximation and Rayleigh–Gans–Born approximation, is an approximate solution to light scattering by optically soft particles. Optical softness implies that the relative refractive index of particle is close to that of the surrounding … See more The validity conditions for the approximation can be denoted as: $${\displaystyle n-1 \ll 1}$$ $${\displaystyle kd n-1 \ll 1}$$ $${\textstyle k}$$ is the wavevector of the light ( See more • Mie scattering • Anomalous diffraction theory • Discrete dipole approximation See more Rayleigh–Gans approximation has been applied on the calculation of the optical cross sections of fractal aggregates. The theory was also applied to anisotropic spheres for nanostructured polycristalline alumina and turbidity calculations on biological structures … See more http://www.astro.spbu.ru/DOP/3-REVS/KHLEB1/node13.html
