Abstract

The problem of determining the terminal impedance values of a lossless nonuniform transmission line is addressed. The transmission line is assumed to have discontinuities at input and output with local reflection coefficients $\\Gamma _{1}$ and $\\Gamma _{2}$ , respectively. A set of formulas is given which allows $\\Gamma _{1}$ and $\\Gamma _{2}$ to be recovered once high-frequency data for $S_{11}$ ( $\\omega$ ) is specified; the formulas extend the generality of earlier theory to the case where $\\Gamma _{1}$ or $\\Gamma _{2}$ may be either positive or negative. It is also shown that $S_{11} (\\omega )$ ) magnitude and phase information is necessary to uniquely determine $\\Gamma _{1}$ and $\\Gamma _{2}$ .
