✦ Synopsis

The possibility of finding an analytic Green dyadic expres-T sion for a class of bianisotropic media, defined by the relations ⑀ s , s x = I q uu , and s z = I q uu between the medium parameter dyadics, is studied. It is shown that the determinant of the dyadic Helmholtz operator, an operator of fourth order, can be expressed as a product of two second-order operators. A method for finding the solution for the Green dyadic in the form of infinite series in terms of powers of the dimensionless parameter r ⑀ is gi¨en. For small ¨alues of the o o parameter, a two-term approximation is seen to take a simple analytic form. As an Appendix, another approach through the Fourier transformation is briefly discussed. Dyadic formalism is applied throughout in the analysis.

In this paper, we in¨estigate the Green's dyadics for a homogeneous bianisotropic medium where the material dyadics are of T the form s ⑀ q ab, s x = I q bb, and s z = I q aa. We will show that the Helmholtz determinant operator still can be factorized for this medium. The scalar Green's function of

The claim of Liu et al. in a recent paper in this journal that rigor is lacking and something is amiss in pre¨iously deri¨ed expressions of the infinite-medium dyadic Green's functions of a homogeneous, isotropic chiral medium is shown to be without any substance. As a consequence, the paper by Liu
