Effects of losses on the transmission and reflection in the single-negative materials

In this work, we investigate the angular dependence of transmission and reflection in the single-negative (SNG) materials. We consider a model structure of a SNG bilayer which consists of the epsilon-negative (ENG) and mu-negative (MNG) layers. The wave transmission and reflection properties due to the losses from the ENG and MNG materials are specifically investigated. With the presence of losses in the ENG and MNG materials, some unusual wave properties will be explored and numerically demonstrated.
