部分填充电各向异性介质波导的直线法

文本引用直线法,分析了一般的部分填充电各向异性介质的波导的色散特性。波动方程仅在一个方向上进行离散化,这样就产生了微分——差分方程,可以解析求解。并推导出了一般的色散特性方程。最后,为了证实本方法的有效性,对各向同性介质波导进行了计算并与精确解进行了比较,结果极为一致。同时,对部分填充电各向异性介质波导进行了计算。

The Method of Lings for Partly Filled with Electric Anisotropic Dielectric Waveguides

In this paper the method of lines is quoted.The partly filled with electric anisotropic dielectric waveguides are analyzed.The wave equation is dis- cretized in only one direction,and the differential-difference equation is yielded and can be solved analytically.The equation of calculating the dispersion chara- cteristics is deduced.At last,in order to demonstrate the strength of the present method,numerical results are shown for a rectangular waveguide filled with electric isotropic dielectric.Numerical results of the present method coincide with those of the analytical method.The same time,numerical results are shown for a rectangular waveguide filled with electric anisotropic dielctric.
