| 摘 要： | 系统研究了含色散左手材料作为芯层的非对称5层平板波导TE波的传输特性,重点讨论了芯层色散、芯层厚度和覆盖层折射率对波导的影响,并与无色散5层平板波导做了比较。研究表明,导波和表面波都可以在这种波导中传播;TE0模只有表面波,TEm（m〉1）模只有导波,TE1模既有导波又有表面波;TEm（m≥1）各模均存在双模现象。

| Abstract: | Propagation properties of the TE mode for asymmetrical five-layer slab waveguide with left-handed materials containing dispersion as core layer was studied.The influences on core layer′s dispersion,thickness and cover refractive index for waveguide were concentrated.And the results were compared with five-layer slab waveguide with left-handed dispersionless material.The results prove that guided and surface waves can both propagate in the waveguide;TE0 mode only has surface waves,TEm（order m1） are guided waves,TE1 modes not only have guided modes,but also the surface modes,and there exist two-mode phenomena.In all TEm（order m≥1） modes exist two-mode phenomena. |
