    In this letter, the standard theory of small reflections (TSR) is generalized for the case of multi-section transformers, composed of conjugately- characteristic-impedance transmission lines (CCITLs) connected in cascade, with small discontinuities. Using the assumption of small reflections, the total voltage reflection coefficient looking into the input of the transformer can be approximated, resulting in the TSR for multi-section CCITL transformers with small discontinuities. Numerical results, some physical interpretations and potential applications of results will be discussed in this letter. © 2008 IEEE.

    The bi-characteristic-impedance transmission lines (BCITLs) are generally lossy transmission lines that possess different complex characteristic impedances for waves propagating in forward and reverse directions. Because of complicated equations associated with BCITLs, a graphical tool is necessary in the analysis and design. In this article, the standard T-chart developed for conjugately characteristic-impedance transmission lines (CCITLs) is generalized to treat BCITL problems, called a generalized T-chart. It is found that the way of using this new graphical tool is similar to that of the standard T-chart. However, the magnitude of the voltage reflection coefficient associated with BCITLs may be greater than unity for some passive load terminations. An example of using a generalized T-chart is provided in this paper. © 2007 Wiley Periodicals, Inc.
