Green's dyadics for a class of bi-anisotropic media with nonsymmetric bi-anisotropic dyadics

In this contribution the Green's dyadics for a class of nonreciprocal bi-anisotropic media are constructed, The considered media are more general than some classes of uniaxial bi-anisotropic media for which the Green's dyadics are presently known in closed form. The material dyadics are of the form <(epsilon)under bar> = <epsilon(I)under bar>, <(mu)under bar> = <mu(I)under bar>, <(xi)under bar> = x x (I) under bar + xi u(z)u(z) and <(zeta)under bar> = z x (I) under bar + zeta u(z)u(z). The <(xi)under bar> and <(zeta)under bar> dyadics give rise to the nonreciprocity of the medium. It will be shown that the final Green's dyadics can be expressed as an infinite series of exponential integrals. The Green's dyadics are constructed in space domain using dyadic analysis.
