报道一种灵活、交互和自动化的系统，它以矢量有限无法为基础，并在IMSL的PDE/Protran题解环境中实现.用它分析各向异性光波导，得到了各向异性介质矩形波导中所有传播模式的数值结果，以及采用传播常数和模场分布二种形式评价这个方法的精度，并与早期的研究结果加以比较.

This peper reports an flexible, interactive and atuomatic system, based on the vector finite element method, and implemented within IMSL'S PDE/Protran problem solving environment. Numerical results for all Propegsting modes in an anisotropic dielectric rectangular waveguide are presented and verified through compeison with an earlier study (where, in fact, fewer modes were found). Furthermore, in comparison with other studies, the evaluation of accuracy of the method is demonstrated in terms of both propagation constants as well as modal field profiles. These results also clearly illustrate the speed and the ease of use of the modified WAVEGIDE program.
