The efficiency of interaction of radiation with a particle and hence its optical properties depend on the particle chemical composition, size, shape, structure, etc. ... Particle size expressed in units of the wavelength of incident radiation, together with chemical composition, most strongly affects the optical properties of a scatterer. ... There are many methods to solve the light-scattering problem for a homogeneous spheroid (our survey of the light-scattering methods see here ). ...

We studied the radiative transfer in a spherical, two-phase clumpy medium, in which coherent, nonconservative scattering is the dominant opacity source and where the source of photons is situated at the center. ... We examined in detail the cloud mass spectrum, the distribution of optical depths, and the apparent fractal nature of the projected cloud structures. ... The expected reddening is substantially reduced for clumpy media. ...

... the radiative transfer equation (RTE) for the randomly-irregular magnetized plasma has been derived on the base of general grounds of the multiple scattering theory . ... Solutions of several absolute tasks of the scattering theory have been obtained (on the optical depth of the ionospheric plasma layer, on the value of radio wave anomalous attenuation, on anomalous refraction, on the backscattered signal intensity for the source being placed within a plasma layer). ...

... In this section, we develop a physical model of the secondary as a disk that is centrifugally supported in the radial direction and hydrostatically supported in the vertical direction. We assume that the disk is vertically isothermal and well mixed. ... where is the mean molecular mass of the gas, is the orbital period at the outer edge of the disk in years, and all of the mass of the secondary has been assumed to be concentrated near its center, so the Keplerian approximation is valid. ...

... Reflection nebulae, like the one seen around the Pleiades star cluster, provide natural laboratories for the study of this scattering phenomenon through the measurement of nebular brightness at various wavelengths. ... In the Pleiades this is accomplished with the aid of 21cm neutral Hydrogen emission maps and interstellar absorption spectra toward stars in the region, which together constrain the scattering geometry. ...
