Abstract

Experimental results on energy and polarization characteristics of the radiation reflected by a layer containing oriented particles are presented. Two models of surface layer are considered: isotropically absorbing particles (model 1), and anisotropically absorbing particles (model 2). Model 1 refers to a layer containing (gamma) -Fe₂O₃ particles with different orientations. Estimates of the particle orientation degree were made from the photomicrographs taken at 1030x magnification. Model 2 refers to a polaroid film containing fully oriented (B equals 0.99) needle-like herapathite microcrystals.
