Effective absorption coefficient of a selective medium within a finite spectral range with regard for scattering

The effect of scattering on the lineshape of outgoing radiation for the regular absorption band model is investigated for the model of a homogeneous plane-parallel radiating, absorbing, and scattering layer with transparent boundaries. The investigation is based on numerical solution of the integrod...

Description
Summary:The effect of scattering on the lineshape of outgoing radiation for the regular absorption band model is investigated for the model of a homogeneous plane-parallel radiating, absorbing, and scattering layer with transparent boundaries. The investigation is based on numerical solution of the integrodifferential equation of radiation transport. Based on an analysis of results obtained, methods more accurate than the known ones are proposed for calculation of the absorption coefficient by a selective component of the medium averaged over a finite spectral range.[PUBLICATION ABSTRACT]
