Light scattering Rayleigh-Debye approximation

Light scattering by a dipole in a plane is considered. Colloidal scattering is discussed using the Rayleigh-Debye approximation, which holds for optically-soft any-form particles comparable with the wavelength. 

Light scattering in liquids within the critical region is described with the Rayleigh-Debye approximation including the correlation functions formalism. 

For time-averaged light-scattering in the Rayleigh-Debye approximation, equation (18) reduces to ... 

Mie wrote the scattering and absorption cross sections as power series in the size parameter 0, restricting the series to the first few terms. This truncation of the series restricts the Mie theory to particles with dimensions less than the wavelength of light but, unlike the Rayleigh and Debye approximations, applies to absorbing and nonabsorbing particles. 

In Rayleigh-Debye s approximation, light scattering has been studied on... 

In conclusion, we present summary tables of the most important formulae of light scattering in Rayleigh s and Rayleigh-Debye s (Rayleigh-Debye-Hans ) approximations as a supplement to the topic Light scattering (Tables 2.1-2.4). 

In the nearest vicinity of the spinodal, concentration fluctuations become correlated, and it is necessary to pass from Rayleigh-Einstein s scattering to Rayleigh-Debye .s approximation for the correct description of light scattering. 

The approaches of colloidal optics are required for analysis of light scattering on heterogeneous gels. In particular, Rayleigh-Debye s approximation with the correlation function formedism finds application (see subsection 2.1.2) (Gallacher and Betterheim, 1962 Bueche, 1970 Pokrovski et al., 1976 Volkova et al., 1987).
