Estimation of the transport properties of strongly scattering dense random media by measuring coherent backscattering

摘要

The transport properties of densely packed layers of titanium dioxide (rutile) powder are studied in visible and near infrared region by measuring coherent backscattering (CBS). Fitting of the experimental data with the coated coherent potential approximation led to evaluation of the transport parameters (such as transport mean free path and effective refractive index) of studied samples without a-priori knowledge of the optical properties of scattering particles.
