Anisotropy and Interference in Wave Transport: An Analytic Theory
| Abstract | A theory is presented which incorporates the effect of dielectricanisotropy in random multiple scattering media. It predicts anisotropicdiffusion, and a deflection of the diffuse energy flow in anisotropicslabs in the direction parallel to the slab. The transmittanceintegrated over all incoming and outgoing directions scales with thetransport mean free path along the surface normal. The escape functionin anisotropic dielectrics is no longer bell shaped. In this modelanisotropy facilitates Anderson localization. |
