非互易网络的无耗约束条件

该文论述了在非互易条件下，无源无耗网络的各种约束表征：例如，阻抗Z]矩阵可以存在实部。它并不与能量定律相悖,即在这种情况下，阻抗矩阵中的电阻并不代表损耗，其负阻也不表示有源增益；传输A]矩阵也反映出|detA]|=1的似互易特性。文中给出了具体实例。

Lossless constraint conditions of non-reciprocal networks

The lossless constraint conditions of the non-reciprocal passive networks are studied in this paper. It is shown that the impedance matrix Z] of a non-reciprocal lossless network has the real part, but it is compatible with the law of conservation of energy. In the non-reciprocal case, the positive resistances of the impedance matrix do not represent the loss of the network, and the negative resistances do not represent the active gain. In addition, the transmission matrix A] has the characteristic of |detA]|=1, which is called as the quasi- reciprocity. The realistic examples are given in this paper.
