摘要
通过引入对应于原有系统的伴随系统，推导出了有耗不均匀各向异性波导系统的变分方程。对满足γａ＝ （－ γ）σ限制条件的伴随场存在的条件进行了分析，给出了不同情况下伴随场与原有场的关系式。利用有限元方法对铁氧体移相器进行了计算分析。
The variational equation for the lossy inhomogeneous anisotropic dielectric waveguide is derived by introducing an adjoint system corresponding to the original system. In addtion, existence of the adjoint fields that satisfy the restricted condition γ a=(-γ) σ is analysed and the relationship between the original field and adjoint field is presented in different situation. The ferrite phase shifters are analysed by means of the finite-element method. The theory is verified by the result of the calculation.
