Iv. Lindell et Ws. Weiglhofer, GREEN DYADIC AND DIPOLE FIELDS FOR A MEDIUM WITH ANISOTROPIC CHIRALITY, IEE proceedings. Microwaves, antennas and propagation, 141(3), 1994, pp. 211-215
A closed-form expression is derived for the Green dyadic corresponding
to a reciprocal bianisotropic medium with isotropic permittivity and
permeability and arbitrary anisotropic chirality. Such a medium can be
approximated, for example, by inserting in an isotropic host medium a
n equal number of similar right- and left-handed metal helices with su
itable orientations. The solution is applied to determine the electric
field of an electric dipole embedded in such a medium. Evaluation of
its far-field shows that the wave is split into two plane waves with d
ifferent wave-normal directions.
