Abstract : A generalized theory of coupled modes of propagation is applied to the study of interactions in distributed microwave devices. In Section II-A a technique is discussed which is suitable for the analysis of non-uniformly coupled systems characterized by the coupled mode matrix equation dx/dz = -iR(z)x where dR/Dz = (A,R) and A is a constant matrix. In Section II-B the theory of pairwise coupling is extended to include the possibility of cross-conjugate modes.An alternative view of this situation interprets it as certain rather special types of multiplet coupling. In Section II-C, theorems are proved that were inferred in Section II-B. The proof is probably of mostly academic interest, but it does give some insight into the nature of the problem. In particular, the proof demonstrates the possibility of removing some of the limitations imposed in Section II-B, which were introduced because of the particular application being considered there.
