On the basis of complet ' : ly analyses about dual - m ( ) de phase shiftcrs , the finite - element formulation derives the variational principle for non - se1fadjoint electromagnetic problems which is microwave propagaticn in a aniso1ropic media loaded waveguide . then , the variatonal problem is approximated by a matrix eigenvalue problem 在此基礎上,詳細討論了利用有限元分析法這一強有力的工具來分析波導中填充各向異性介質的問題,導出了基于變分原理的泛函和有限元方程。
