Abstract :
An explicit expression for the Green dyadic corresponding to the axially chiral reciprocal uniaxial bianisotropic medium is derived through dyadic analysis with no recourse to Fourier transformations. The result is a generalization of the Green dyadic corresponding to the uniaxial anisotropic medium, which has been known for decades. As a verification, expressions for the field due to an axial dipole are derived and compared to those derived recently through other methods. The medium under study can be realized by laying axially parallel metal helixes in random locations in a host material. Such a medium has recently been shown to possess important polarization-transforming properties
