Polarimetric scattering by a bio-medium with anisotropic biomolecules

The bio-media are made of anisotropic molecules. Using a simple ellipsoid model, the scattering of bio-medium with anisotropic bio-molecule is investigated theoretically. The scattering fields and Mueller matrices are derived from fundamental electromagnetism theory. The bio-medium is modeled as a system of non-correlated anisotropic molecules. Based upon a statistical model of anisotropic distribution, the scattering Mueller matrix is derived. The single and double photon scattering models are investigated. Double scattering is more important for high density scattering medium. For incident light with pure polarization, such as linear and circular polarizations, the results of molecular shape-dependent differential and total scattering cross-sections are reported. This theory can provide a simulation tool for investigating the scattering and polarization/depolarization effect in the highly scattering bio-medium.
