| 摘 要： | 在TE极化情况下，对芯层为左手材料，衬底层和覆盖层均为金属的对称平板波导（Metal—LHM—Metal）的传输特性进行研究．利用传输矩阵推导其导波条件，并采用图解法对其不同的传播模式和相应的电场分布进行分析．Metal—LHM—Metal波导结构不存在基模，支持导波同时也存在表面波，阶数m对电场分布有显著影响．

| Abstract: | The propagation properties of waveguide in TE modes were studied on the three-layer symmetric slab made of left-handed material surrounded by metal.The waveguide conditions of TE modes were deduced by transmission matrix.Different propagation modes and corresponding transverse profiles of electric field were analyzed using graphic method.The results show that the fundamental mode TE0 does not exist,which can support surface wave modes,and there is a significant effect on transverse profile of order m and so on.This study will play a theoretical guidance for the research of waveguide containing left-handed materials |
