An efficient, accurate, and automated vectorial finite-element software package (named WAVEGIDE), which is implemented within a PDE/Protran problem-solving environment, has been extended to general multilayer anisotropic waveguides. With our system, through an interactive question-and-answer session, the problem can be simply defined with high-level PDE/Protran commands. The problem can then be solved easily and quickly by the main processor within this intelligent environment. In particular, in our system the eigenvalue of waveguide problems may be either a propagation constant (β) or an operated light frequency (F). Furthermore, the cutoff frequencies of propagation modes in waveguides can be calculated. As an application of this approach, numerical results for both scalar and hybrid modes in multilayer anisotropic waveguides are presented and are also compared with results obtained with the domain-integral method. These results clearly illustrate the unique flexibility, accuracy, and the ease of use f the WAVEGIDE program.
一个高效、准确且自动化的矢量有限元软件包（名为WAVEGIDE）已被扩展到通用多层各向异性波导，该软件包是在PDE/Protran问题求解环境中实现的。在我们的系统中，通过交互式问答环节，可以使用高级PDE/Protran命令简单地定义问题。然后，在这个智能环境中，主处理器可以轻松快速地解决该问题。特别是，在我们的系统中，波导问题的特征值可以是传播常数（β）或工作光频率（F）。此外，可以计算波导中传播模式的截止频率。作为这种方法的一个应用，给出了多层各向异性波导中标量模式和混合模式的数值结果，并与用域积分法获得的结果进行了比较。这些结果清楚地说明了WAVEGIDE程序独特的灵活性、准确性和易用性。
