  2. Smith chart - Wikipedia

    en.wikipedia.org/wiki/Smith_chart

    Using the Smith chart, the normalised impedance may be obtained with appreciable accuracy by plotting the point representing the reflection coefficient treating the Smith chart as a polar diagram and then reading its value directly using the characteristic Smith chart scaling. This technique is a graphical alternative to substituting the values ...

    In the mathematical field of graph theory, a Smith graph is either of two kinds of graph. It is a graph whose adjacency matrix has largest eigenvalue at most 2, [ 1 ] or has spectral radius 2 [ 2 ] or at most 2. [ 3 ]

    Volpert nomogram, a diagram better known as "Smith chart" coinvented by Russian engineer Amiel Rafailovich Volpert (Амиэ́ль Рафаилович Во́льперт) Volpert graph (chemistry) , a chemical reaction graph by Russian mathematician Aizik Isaakovich Volpert ( Айзик Исаакович Вольперт )

  5. Nomogram - Wikipedia

    en.wikipedia.org/wiki/Nomogram

    A Smith chart to calculate electrical impedance with no values plotted; although not a nomogram, it is based on similar principles. Like a slide rule, a nomogram is a graphical analog computation device. Also like a slide rule, its accuracy is limited by the precision with which physical markings can be drawn, reproduced, viewed, and aligned.
