The vertical eigen-mode was solved by one-dimensional finite element method (FEM).
垂直特征模式用一维有限元计算。

From these expressions the dyadic Green's function for a dielectric waveguide can be obtained if the eigen-mode of the waveguide are given.
根据这个表达式，只要给定介质波导的本征模，就可以得到该波导的并矢格林函数。

It is shown that the expression of electric-type dyadic Green's function is the sum of an eigen-mode expansion containing nine dyadic components and a singular term.
