| 摘 要： | 采用直线法与等效传输线法相结合的方法分析了平面波导结构的色散特性,通过实验研究和理论分析,在证明该方法有效性的同时,对该算法在实际应用中存在的基本问题进行了处理,得出一般性原则,如计算区域边缘条件的设置、结果精度与划线数N的关系和屏蔽面位置的影响等。在此基础上,对几种常用的平面波导结构进行分析,并证明了其正确性。同时,为该方法在多介质层多导体结构分析中的应用提供了理论指导。

| Abstract: | A hybrid method,which combines the line method with the method of equivalent transmission lines, for calculating the dispersion of planar waveguide structures is presented.Further study of this method is made through experiments and theories to testify its efficiency. What's more, some potential problems in practical applications are described, such as the edge condition,the correlation between the number of lines (N), the precision of the result, and the location of the shield wall,etc. Then some useful planar waveguide structures are calculated to testify these conclusions. Finally, a kind of multi-layer multi-conductor structure is analyzed. |
