Factorization and Green Dyadics for a New Class of Bi-Anisotropic Media Using Duality

Abstract

In this paper we will study the Green dyadics and the factorization of the Helmholtz determinant operator for a new class of homogeneous bianisotropic media. That new class of media is derived from previously studied media using a rotational duality transformation. The new class of media is very general and contains many other, previously studied classes, as special cases. The Green dyadics are expressed in a form that contains a one-dimensional inverse Fourier transformation that, in general, cannot be evaluated in closed form.
