Spinor formalism of the scattering problem solution upon the chiral and bi-isotropic objects

Summary form only given. Much effort have been made in the study of the scattering, absorption and other diffraction properties of objects made of or coated by various composite and optically active materials (chiral, bi-isotropic, bianisotropic). To effectively solve the scattering problem of such objects in the case of a complex geometry and excitation type, the further development of the existing methods is needed. This may be done in the way of a proper formulation and solution of the scattering problem. In this article, a spinor formalism is suggested to state and solve the scattering problem upon the bi-isotropic (in particular, chiral) objects through the method of auxiliary sources (MAS), suitable for this aim. Some results of the study are demonstrated
