| 摘 要： | 采用广泛应用于波散射分析的Ｔ矩阵方法，研究了介质波导中导波与多个非均匀性的相互作用问题。原理上讲，文中的分析适用于任意结构的介质波导和任意形状的非均匀性。当介质波导为单模圆柱光纤时，给出了由多个非均匀性所引起的ＨＥ＿（１１）模传输和反射系数的解析表达式，这些表达式为数值上研究非均匀性对光纤传输特性的影响提供了理论依据。

| Abstract: | Based on T- matrix approach for wave scattering,the problem of multiple scat- tering of gnided waves by inhomogeneities in dielectric waveguides is analyzed.In principle,thegiven analysis can be applied to the inhomogeneities of arbitrary shape and the waveguide of ar- bitrary geomctry.As the waveguide is a monomode optical fiber, the analytical expressions ofthe transmission and reflection coefficients for HE_(11) mode are given. These expressions providethe theoretical basis for studying the effects of the inhomogeneities on the transmission character- istics of the optical fibers. |
