About this package

This package enables drawing of Smith charts, admittance charts, and immittance charts.

Functions

• SmithPlot[{v11, v12, ...}, {v21, v22, ...}]
  Plots a Smith chart.
• AdmittancePlot[{v11, v12, ...}, {v21, v22, ...}]
  Plots an admittance chart.
• ImmittancePlot[{v11, v12, ...}, {v21, v22, ...}]
  Plots an immittance chart.
• SmithChart[{v11, v12, ...}, {v21, v22, ...}]
  Generates a graphic primitive of a Smith chart.
• AdmittanceChart[{v11, v12, ...}, {v21, v22, ...}]
  Generates a graphic primitive of an admittance chart.
• ImmittanceChart[{v11, v12, ...}, {v21, v22, ...}]
  Generates a graphic primitive of an immittance chart.
  
  

Examples

Loading the package

<<"(path to the appropriate directory)/Smith.m"

When you have put the file "Smith.m" under, say, c:\math\packages, the following command will do.



<<"c:/math/packages/Smith.m"

Drawing of a Smith chart

When you want to visualize iso-resistance circles of values 0, 0.5, 1, 2, and 4, iso-reactance circles of values -4, -2, -1, -0.5, 0, 0.5, 1, 2, and 4, type as follows.



nres = {0, 0.5, 1, 2, 4};
nrea = {-4, -2, -1, -0.5, 0, 0.5, 1, 2, 4};
SmithPlot[nres, nrea];

Then, what you get is as follows:



Admittance charts as well as immittance charts can be obtained in a similar way, as follows.



AdmittancePlot[{0, 0.5, 1, 2, 4}, {-4, -2, -1, -0.5, 0, 0.5, 1, 2, 4}];



ImmittancePlot[{0, 0.5, 1, 2, 4}, {-4, -2, -1, -0.5, 0, 0.5, 1, 2, 4}];
