COHERENT BACK SCATTERING IN HETEROGENEOUS SYSTEMS

The investigation objects are the solutions of the latexes and mixtures of the nematics MBBA+EBBA. The aim is to construct the theory of the coherent back light scattering and to design the angular relation of the back scattering peak for all the possible polarization combinations of the falling and scattering waves for systems of the isotropic and anisotropic scatterers. The multiple ligth scatering problem for the point isotropic and anisotropic scatterers possessing the half-space has been solved. The angular distribution of the intensity in the polarized and depolarized components has been designed. The new result has been specified: the back scattering peak in the depolarized component is absent for anisotropic scatteres. The coherent back scattering on the non-oriented nematic liquid crystal has been investigated, the agreement of the theory with experience has been obtained.Available from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
