摘要：

The guided modes in a left-handed material (LHM) asymmetric slab waveguide are studied in this paper. Dispersion properties of electromagnetic guided waves are discussed by introducing three normalized parameters. The guidance conditions of guided modes in waveguide are determined by using a graphical method. Then we put emphasis on the surface wave modes with respect to different waveguide parameters and structures. The power flux in LHM asymmetric waveguide according to the Poynting vector is investigated in the end.
