WebMar 17, 2024 · 2.1 The Rayleigh–Gans approximation for single particles. The basis of the SSRGA methodology is the Rayleigh–Gans approximation (RGA), which applies to “optically soft” particles. This condition states that the various parts of an arbitrarily shaped particle only interact with the incident wave, and the coupling among its scattering elements can …
