1.1, provides an interesting example of a chart which was used by mariners and astronomers for over 20 centuries, even though the mathematics was well understood. The ancient astrolabe, a Renaissance version of which is shown in Fig. For example, a simple physical relationship such as that expressed by Ohm's law does not require a graphical representation for its comprehension or use, whereas laws of spherical geometry which must be applied in solving navigational problems may be sufficiently complicated to justify the use of charts for their more rapid evaluation.
Usually the more complex the law the more useful is its graphical representation. The physical laws governing natural phenomena can generally be represented either mathematically or graphically.

Several improvements in terms of rendering/visualizations, helpful both in actual design and learning the 2D Smith and 3D Smith chart concepts (axes system, “Greenwich” constant resistance meridian, surface transparency, etc.).Ībove is an example of one of these new features showing a 3D frequency sweep representation over S11.

Different models of definitions are used (shunt inductor model, series inductor model).

Now, based on the article, "Reconfigurable RF Electronic Functions Designed with 3D Smith Charts in Metal-Insulator-Transition Materials," several new features have been added to the 3D Smith chart version 1.02 Windows 64-bit compatible tool. (North pole: perfect match, South pole infinite mismatch). The South-represents active areas with negative resistance, North areas represent passive with positive resistance, East inductive and West capacitive. The original 3D Smith chart tool (version 1.01) extended the Smith chart capabilities for the first time since the 1939s to make it usable for circuits with negative resistance based on a unit sphere that plots circuits with reflection coefficient magnitudes larger than 1 by mapping them as arcs on the 3D sphere. 3D Smith chart announces a new version (1.02) of the 3D Smith chart with new features.
