Findings from National Aeronautics and Space Administration in science reported

  2008 OCT 20 - (VerticalNews.com) -- According to recent research from the United States, "This paper continues a systematic theoretical analysis of electromagnetic scattering by a group of arbitrarily sized, shaped, and oriented particles embedded in an absorbing, homogeneous, isotropic, and unbounded medium."

  "The previously developed microphysical approach is used to derive the generalized form of the radiative transfer equation (RTE) applicable to a large group of sparsely, randomly, and uniformly distributed particles. The derivation of the RTE directly from the macroscopic Maxwell equations yields unambiguous and definitive analytical expressions for the participating quantities and thereby fully resolves the lasting Controversy Caused by the conflicting outcomes of several phenomenological approaches," wrote M.I. Mishchenko and colleagues, National Aeronautics and Space Administration.

  The researchers concluded: "Published by Elsevier Ltd."

  Mishchenko and colleagues published their study in the Journal of Quantitative Spectroscopy & Radiative Transfer (Multiple scattering by particles embedded in an absorbing medium. 2. Radiative transfer equation. Journal of Quantitative Spectroscopy & Radiative Transfer, 2008;109(14):2386-2390).
