Application of forward scattering renormalization to scattering in turbid media
Abstract
The conventional waveintegral equation in electromagnetic scattering, consisting of a sum of directlyreceived vacuum field plus a scattered field that sums weighted vacuum spherical waves from each scatterer, is replaced by one in which renormalized fields containing part of the multiplyscattered energy replace the vacuum fields. A firstorder approximation in the renormalization equation is applied to bistatic (largeangle) scattering from weak random fluctuations of the permittivity in a distant volume, and to a sparse monodisperse distribution of isotropic particles to yield scattering cross sections with extended validity for the direct polarization. A similar correction is introduced for the cross polarization in the case of backscatter. Differences with other calculations are noted.
