In this paper, we investigate the reflection behavior of electromagnetic waves incident on an interface between an isotropic medium and a general electric-magnetic uniaxial lossy medium. We analyze this interface by applying the general SH/DB boundary conditions and discuss its response for some particular cases as well. The propagation of both homogeneous and inhomogeneous waves in a uniaxial lossy medium is discussed. It is found that for low losses the uniaxial medium under consideration is very suitable while for higher losses it decreases its appeal for the realization of the SH/DB medium. The results obtained in the lossy case are compared with those of the lossless one, presented in the literature. Many metamaterials proposed can be homogenized as electric-magnetic uniaxial media. We investigate their characteristics and try to understand their limitations due to the presence of losses.
