Angular polarization characteristics of diffusely of diffusely reflected radiation in semi-infinite media and in media with a finite optical thickness

Abstract: The paper theoretically investigates the polarization characteristics of diffusely reflected and transmitted secondary radiation when illuminating a light-scattering turbid medium and a medium with high dielectric permittivity by monochromatic, unpolarized radiation. Angular polarization characteristics of secondary radiation in the model of a semi-infinite medium and a medium with finite optical thicknesses are compared. The positions of neutral Babine, Brewster, and Arago polarization points in turbid media and in media with high dielectric permittivity are investigated, taking into account the mirror reflection of radiation from the internal boundary of the medium. The conditions for the appearance of neutral points depending on the angles of illumination and the multiplicity of scattering are analyzed.
