A model which represents the behavior of radiation in two media of different density is the one that assumes photons only interact within the target, i.e. those photons escaping towards the empty half-space may suffer absorption but never return back to the target. This paper discusses the differences between the scalar and vector equations for this model, in plane geometry for a monochromatic slant source. The focus is on the differences between the scalar equation for average polarized radiation and the first Stokes component, which is analogous to the detected intensity in the vector equation. It is shown that the equation is linear, the single equation for the intensity is nonlinear due to the coupling in the scattering term.

Abstract
A model which represents the behavior of radiation in two media of different density is the one that assumes photons only interact within the target, i.e. those photons escaping towards the empty half-space may suffer absorption but never return back to the target. This paper discusses the differences between the scalar and vector equations for this model, in plane geometry for a monochromatic slant source. The focus is on the differences between the scalar equation for average polarized radiation and the first Stokes component, which is analogous to the detected intensity in the vector equation. It is shown that the equation is linear, the single equation for the intensity is nonlinear due to the coupling in the scattering term.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
