分析双模铁氧体器件时常用到极化变换矩阵。无损耗时极化变换矩阵为酉矩阵；互易时，正、反向极化变换矩阵互为转置。本文还叙述了非互易网络和互易网络极联时总网络互易性的判定方法。

Polarization transfer matrices are used for analysing dual-mode ferrite devices frequently. A lossless polarization transfer matrix is a unitary matrix, and reciprocal forward and backward polarization transfer matrices are transposed each other. For the case of reciprocal and nonreciprocal networks in cascade, a method determining the reciprocal property of the resultant network is also presented.
