WebMay 24, 2016 · One method that takes the configuration of a particle into account is the Rayleigh–Gans theory (e.g., Bohren & Huffman 1983). The Rayleigh–Gans theory, or the first Born approximation, is applicable to an arbitrarily shaped particle as long as the particle's refractive index is close to that of a vacuum, i.e., it is optically soft. WebThe Self-Similar Rayleigh-Gans Approximation. The Self-Similar Rayleigh-Gans Approximation (SSRGA) provides a means to compute the scattering properties of aggregated ice particles and snowflakes in the microwave and millimetre parts of the spectrum. In this regime the soft sphere/spheroid approximation tends to significantly …

WebThe scattering matrix, differential cross section, and the total cross section for a small nematic droplet are derived in the Rayleigh-Gans approximation. Different nematic director configurations are considered for the droplet. Those studied are the configurations which result in a spherical droplet from different molecular anchoring angles at the droplet wall.
