A generalized ZY Smith chart for solving nonreciprocal uniform transmission‐line problems

Abstract Nonreciprocal transmission lines have found various applications in microwave technology. Because the governing equations of nonreciprocal transmission lines are quite complicated, the need for a graphical tool to assist in the analysis and design of nonreciprocal devices is obvious. The Smith chart has shown to be a very useful graphical tool when solving reciprocal uniform transmission‐line problems. However, the Smith chart needs to be modified for nonreciprocal transmission lines; this is called a generalized Smith chart. This novel chart can be easily generated using Matlab. It is found that the ZY Smith chart is a special case of a generalized ZY Smith chart. © 2004 Wiley Periodicals, Inc.
