摘要
本文用已知截面的波导匹配各种形状介质波导,并分别用面积补偿和能量补偿的思想,具体计算了几种形状的波导,所得公式简单,计算结果与精确值符合甚好.
In this article,We provide a method to use the known wareguide to appro- ach the unknowns.For example,we have calculated the dispersion charcteristics of the waveguide with cross-section trangle,circle,etc.The formulas are simple and casy to apply.The results agree very well with the computer aided exact numerical analysis.The method can be easily extented to the analysis of any other dielectric waveguides structures.
