EXTENSION OF THE GENERALIZED MULTIPOLE TECHNIQUE TO ANISOTROPIC MEDIAS

This paper presents an extension of the generalized multipole techniqu e (GMT) for 2D anisotropic scatterers. New expansions similar to the B essel multipole expansion are derived for arbitrary anisotropic media. Numerical simulations prove the accuracy and the rapid convergence of these expansions. As the results obtained are extremely accurate, thi s technique is most helpful for the evaluation of reference solutions and for the understanding of the physical interaction of light with ar bitrary anisotropic media.
