The Smith chart graphical equivalent of using the transmission-line equation is to normalise , to plot the resulting point on a Z Smith chart and to draw a circle through that point centred at the Smith chart centre. The path along the arc of the circle represents how the impedance changes whilst moving along the transmission line.
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] The graphs with spectral radius 2 form two infinite families and three sporadic examples; if we ask for spectral radius at most 2 then there are two additional infinite families and three more sporadic examples.
The Smith chart, used by electrical engineers for analyzing transmission lines, is a visual depiction of the elliptic Möbius transformation Γ = (z − 1)/(z + 1). Each point on the Smith chart simultaneously represents both a value of z (bottom left), and the corresponding value of Γ (bottom right), for |Γ |<1.
The Smith Chart allows simple conversion between the parameter, equivalent to the voltage reflection coefficient and the associated (normalised) impedance (or admittance) 'seen' at that port. The following information must be defined when specifying a set of S-parameters: The frequency
Smith diagram or Smith diagramme may refer to: Smith chart , a diagram by American electrical engineer Phillip Hagar Smith, used in electrical engineering Smith fatigue strength diagram [ de ] , a diagram by British mechanical engineer James Henry Smith [ de ] , used in mechanical engineering

Escher , Regular Division of the Plane VI , has this tiling as its underlying structure, with each square tile of a binary tiling (as seen in its quadtree form) subdivided into three isosceles right ...
Volpert graph, Vol'pert graph or Wolpert graph may refer to: Volpert nomogram , a diagram better known as "Smith chart" coinvented by Russian engineer Amiel Rafailovich Volpert ( Амиэ́ль Рафаилович Во́льперт )
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.
