Rayleigh-gans
WebBackscattering properties of dry snowflakes at different microwave frequencies are examined. It is shown that the Rayleigh approximation does not often provide the necessary accuracy for snowflake reflectivity calculations for radar wavelengths used in meteorology; however, another simple approximation, the Rayleigh-Gans approximation, can be safely … WebThe name of Gans is reasonable to leave in the term the RDG theory just for the reason …

WebScattering From Macromolecules. The Rayleigh-Gans-Debye theory is valid for solid dielectric objects such as colloidal particles, whose dielectric properties are well known. For macromolecules, however, dielectric properties are not as well defined because continuum theories don't strictly apply. Small modifications, however, allow for an ... WebThe name of Gans is reasonable to leave in the term the RDG theory just for the reason that due to van de Hulst the term Rayleigh-Gans approximation became widespread, although he did not consider this term to be a good one. The RDG approximation can be obtained in several ways [25,124,274,441].

WebApr 18, 2015 · A widely used approximation in studies relating to small angle differential scattering cross-section of X-rays scattered by interstellar dust grains is the well known Rayleigh-Gans-Debye approximation (RGDA). The validity of this approximation, however, is limited only to X-ray energies greater than about 1 keV. At lower energies, this …
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.
