The Smith chart can be used to simultaneously display multiple parameters including impedances, admittances, reflection coefficients, S n n. A quarter-wave stub is a convenient way of supporting an inner conductor without an insulator, and accessing the inner conductor with water cooling, for example. It was independently devised by Tōsaku Mizuhashi ( 水橋東作) in 1937, and by Amiel R.
Having the ability to design these matching circuits on the fly can be very handy if you ever find yourself working in the RF field both because it can be faster than calculation, as well as being a great tool for visualizing what is going on. The Smith chart (sometimes also called Smith diagram, Mizuhashi chart ( 水橋チャート), Mizuhashi–Smith chart ( 水橋スミスチャート), Volpert–Smith chart ( Диаграмма Вольперта-Смита) and Mizuhashi–Volpert–Smith chart), is a graphical calculator or nomogram designed for electrical and electronics engineers specializing in radio frequency (RF) engineering to assist in solving problems with transmission lines and matching circuits. Overview of stub tuning examples using the Smith chart to match RF lines to various loads.
