回転対称3開孔非可逆回路の固有値の測定法  [in Japanese] New measuring method of Eigenvalues of Nonreciprocal three Ports Network  [in Japanese]

Abstract

従来非可逆回路の固有インピーダンスは各周波数に対し各端子を固有励振し測定していた^<(1)>。その他各固有励振に対する固有周波数を測定する方法もある。しかし、この方法では固有周波数が固有励振により変化するため、フェライトの透磁率の分散特性を換算する必要があった。そこで各開孔に誘電体共振器を付加して、非可逆インピーダンスを摂動により求める方法を提案して実験で確認したものである。

Eigenvalues of three ports network, so far, was obtained by measuring the eigen impedance corresponding to different eigen excitations, when three different phase lines were used. In the propose method, three ports reciprocal network including three dielectric resonators was weakly coupled to two ports, and a nonreciprocal element is connected to a reciprocal network mentioned above. The eigenvalues of nonreciprocal network can be obtained by the perturbation technique using the values of difference of eigen frequencies between the reciprocal circuit and that with the nonreciprocal element.
