A method for analysis of complex transmission coefficients of symmetric matched two-ports

A method for generalized analysis of the transmission coefficients of symmetric matched two-ports is proposed. The method allows fast determination of the values of active and reactive components of input admittances of intrinsic one-ports for even-and odd-mode excitation of the two-port’s ports. The concept of an intrinsic coefficient of a symmetric two-port is introduced. The variation intervals of this coefficient are determined for dissipative, reactive, and dissipative-reactive two-ports.
