Transport mean free path for Magneto-Transverse Light Diffusion: an alternative approach

This article presents a derivation of the transport mean free path for magneto-transverse light diffusion, $\ell^*_\perp$, in an arbitrary random mixture of Faraday-active and non-Faraday active Mie scatterers. This derivation is based on the standard radiative transfer equation. The expression of the transport mean free path obtained previously from the Bethe-Salpether equation, for the case where only Faraday-active scatterers are present,is recovered. This simpler formulation can include the case of homogeneous mixtures of Faraday-active and non-Faraday active scatterers.
