Polarization of waves in reciprocal and nonreciprocal uniaxially bianisotropic media

We. investigate the polarizations of waves in reciprocal and nonreciprocal uniaxially bianisotropic media, whose corresponding chirality parameter and Tellegen parameter appear only in one direction. By analyzing constitutive parameters for generating circularly polarized waves, we find that the optical-activity effects happen in such kind of uniaxially anisotropic chiral media under certain conditions. On the other hand, similar conditions give birth to linearly polarized waves in nonreciprocal uniaxially bianisotropic media.
