Abstract. The results of calculations of dispersive characteristics of a planar waveguide made of the metamaterial with loss are presented in the work, classification of types of waves of such wave guide is given. It is shown that both forward and backward waves can present in such structure, there is a possibility of distribution of waves without attenuation, despite of the presence of losses in a metamaterial, and also there are modes extending with constant phase velocity, which is independent on frequency.

Key words: metamaterials, planar waveguide.
