Abstract :
The reflection behavior of electromagnetic waves incident on an interface of a lossy electric-magnetic uniaxial medium is analyzed. The interface is investigated by applying the general SH/DB boundary conditions and its response is also examined for some particular cases. A condition for the material´s parameters is presented for which a plane wave, in the uniaxial lossy medium, propagates without attenuation. 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.
