Smith Chart

The Smith Chart is a graphical tool for visualizing and manipulating complex impedances and reflection coefficients on transmission lines. Introduced by Phillip Smith in 1939, the chart maps the complex reflection coefficient plane to a circular chart, enabling intuitive graphical analysis of transmission line problems, impedance matching, and resonance conditions. Despite the advent of computers, the Smith Chart remains invaluable for understanding transmission line physics and designing RF circuits.
