非互易網(wǎng)絡(luò)的無耗約束條件
Lossless constraint conditions of non-reciprocal networks
-
摘要: 該文論述了在非互易條件下，無源無耗網(wǎng)絡(luò)的各種約束表征：例如，阻抗[Z]矩陣可以存在實(shí)部。它并不與能量定律相悖,即在這種情況下，阻抗矩陣中的電阻并不代表損耗，其負(fù)阻也不表示有源增益；傳輸[A]矩陣也反映出|det[A]|=1的似互易特性。文中給出了具體實(shí)例。

Abstract: 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 |det[/l]|=l, which is called as the quasi- reciprocity. The realistic examples are given hi this paper. -
