Abstract

In this paper, lossy transmission lines with arbitrary loss are analyzed in detail. Interestingly, analytical results show that the magnitude of the voltage reflection coefficient could be greater than unity for some passive load terminations. However, it can be shown rigorously that the input power is always greater than or equal to the power at the load; i.e., it still satisfied the law of power conservation even when the magnitude of the voltage reflection coefficient is greater than unity. In addition, the Smith chart is also employed to graphically illustrate that the magnitude of the voltage reflection coefficient at some points along lossy transmission lines could be greater than unity for proper load terminations. © 2007 Wiley Periodicals, Inc.
