Application on using the infinite medium vector Green’s function for polarized radiation in a Rayleigh-scattering atmosphere

The radiative transfer equation has wide application fields, such as atmospheric optics, oceanography, biomedical physics, and optical tomography. This paper presents the investigation of the vector radiative transfer equation for polarized radiation transport in optically semi-infinite, homogeneous, Rayleigh-scattering atmosphere with no interior source using an analytical approximation. The spatial attenuation coefficient, the outward-to-inward flux ratio, and the mean cosine, which were defined in terms of the total intensity component, I, were calculated for Rayleigh-scattering case using the infinite medium Green’s function. The behaviors of these parameters were obtained as a function of the optical depth.
