摘要
基于一阶有限元法，运用有限元的外推理论，对用有限元外推法计算波导问题的本征值进行了探讨。算例表明这种方法算法简单且具有高精度性。
On the basis of the method of linear finite element and taking the advantage of the theory of finite element extrapolation,the paper discusses the method for calculating the eigenvalue of waveguide.The results show the method is simple and has higher accuracy.
