Engineering-Style Smith Chart

A Smith chart is a conformal mapping of the complex plane to the complex plane such that the non-negative resistance or conductance half-plane is mapped onto a unit circle. Excepting cases where circuits with gain are being analyzed, all plotting occurs in the non-negative half-plane, permitting a compact nomogram for plotting and computing impedances and admittances. Resistances (conductances) and reactances (suspectances) are normalized by the standard resistance (conductance), which is plotted as 1 on the zero reactance (suspectance) line.
