Rayleigh scattering mechanism
WebThe dynamics of orientational scattering has been discussed on various occasions in the preceding chapter. We shall discuss here the mechanism of Brillouin and Rayleigh scatterings. Stimulated effects in nonlinear optics, such as stimulated Brillouin and Raman scattering in liquids and gases and stimulated thermal Rayleigh scattering, have been … WebRayleigh Scattering: Basic Mechanism One way to understand scattering is as follows: i) The incident E-field induces a time-varying dipole moment in the sphere (recall the electrostatics problem of a dielectric sphere in a uniform E-field from homework 3) ii) The time-varying dipole radiates like a Hertziandipole, and this radiation is the
