![]() ![]() It was independently devised by Tōsaku Mizuhashi ( 水橋東作) in 1937, and by Amiel R. The Smith chart can be used to simultaneously display multiple parameters including impedances, admittances, reflection coefficients, S n n S_. ) The blue circle, centered within the impedance Smith chart, is sometimes called an SWR circle (short for constant standing wave ratio). Smith chart: Upon which this article concentrates. ![]() The complex voltage reflection coefficient Γ \Gamma \, is defined as the ratio of the reflected wave to the incident (or forward) wave. The primary objectives of this article are to review the Smith charts construction and background, and tosummarize the practical ways it is used. Topics addressed include practical illustrations of parameters,such as finding matching network component values. ![]()
