A smith chart can tell you these things and give you hard numbers in a jiffy. For example, a short-circuited stub is just a short circuit seen through a length of transmission line. Place your pencil at the SC point on the chart and move clockwise toward the generator (at the other end of the stub) on the rim by an amount less than a quarter wavelength (180 degrees on the chart). The Smith Chart was originally created many years ago as an RF engineering aid by Phillip Smith of RCA. Actually, Smith may not have been the first inventor of this tool -- a Japanese engineer named Kurakawa independently created a similar chart about a year before Smith. In any event, the Chart is a clever, Concept of Smith Chart (Part 1) | Electromagnetic Theory - Duration: 37:13. GATE ACADEMY 6,833 views

The Smith chart can be used to represent many parameters including impedances, admittances, reflection coefficients, scattering parameters, noise figure circles, constant gain contours and regions for unconditional stability, including mechanical vibrations analysis.[4][5] The Smith chart is most frequently used at or within the unity radius
