对轴向均匀电磁波导的基于势或场的有限元求解器进行了一般分析。导出了一组允许的规范变换的显式方程，随后将其用于识别可能影响当前方法可靠性的副作用。我们表明，可以通过采用矢量势的横向分量分解以及特定的规范选择的增强公式来消除这种限制。数值结果支持我们的发现。
A general analysis of potential- or field-based finite element solvers for axially uniform electromagnetic waveguides is presented. Explicit equations for the set of permissible gauge transformations are derived, which are later utilized to identify side effects that may affect the reliability of present approaches. We show that such limitations can be eliminated by an enhanced formulation employing a decomposition of the transverse components of the vector potential together with a particular choice of gauge. Numerical results support our findings.
