| 摘 要： | 根据新近发展起来的迭代特征函数展开方法(IEEM),提供了一个分析任意非线性平板介质波导中TE波和TM波传播特性的途径。和有限元分析的结果比较,证明该方法在处理此类非线性问题时是非常有效的,而且很容易被推广到各种几何形状的非线性介质波导的分析中去。

| Abstract: | A new treatment for the behaviour of both TE and TM non-linear waves in an arbitrary nonlinear material is given. The treatment is based on a recently developed method-the Iterative Eigen. function expansion method (IEEM). Compared with the results of Finite-element method (FEM), this scheme has proven very successful.It is also easily generalized to other nonlinear behaviour studies for varying geometries. |
