Abstract
AbstractThe 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.
