Copolarized and cross-polarized incoherent specific intensities for waves at oblique incidence upon layers of finitely conducting particles with rough surfaces

Optical and infrared electromagnetic scattering and depolarization by layers of randomly distributed particles of irregular shape and finite conductivity are determined through the use of the equation of transfer. The irregularly shaped particles are characterized by their random rough-surface height spectral density function or autocorrelation function. The extinction cross section and the elements of the scattering matrix in the equation of transfer are evaluated by using a full-wave approach, which accounts for specular point and diffuse scattering in a self-consistent manner. Both single-scatter and multiple-scatter incoherent specific intensities are evaluated for particles with smooth and rough surfaces.
