A visual comparison between voltage and power wave reflection coefficients of microwave circuits

摘要

This paper analyzes and compares voltage and power wave reflection coefficients using a visual representation which fully exploits that both coefficients are directly related to the geometry of direct inversive transformations in the extended impedance plane. In order to compare the two concepts for complex impedance ports, the 3D Smith chart tool is used in premiere. The paper gives a geometrical and more intuitive insight of these two parameters and proposes a novel tool for handling both types of reflection coefficients.
