用有限元法分析有损耗非均匀各向异性波导时，需要进行矢量波分析。在[15]中，从不同的角度比较了用于分析复杂波导结构的现有有限元公式。用有限元法求解非均匀各向异性波导时应注意的特点是：a)处理损耗的能力。b)计算复杂模式的能力。c)求解任意形状波导的可能性d)同时模拟介电和磁的能力e)处理全张量的能力[e]和[p]。f)杂散模式抑制。g)结果特征系统的矩阵稀疏性。h)将频率指定为输入参数，将传播常数求解为特征值解的可能性。
of lossy inhomogeneous anisotropic waveguides by means of FEM, a vectorial wave analysis is required. Existing FEM formulations, useful for analyzing complex waveguide structures, were compared in [15] with regard to different points of view. Features that should be stressed when solving inhomogeneous anisotropic waveguides by FEM are a) Capability of handling losses. b) Ability to compute complex modes. c) Possibility of solving arbitrarily shaped waveguides with d) Ability to model simultaneous dielectric and magnetic e) Capability of handling full [E] and [p] tensors. f) Spurious-mode suppression. g) Matrix-sparsity of the resulting eigensystem. h) Possibility of specifying the frequency as input parameter and solving for the propagation constant as eigenvalue solution.
