Abstract : Computer determined waveguide or transmission line parameters can now be shown on a Smith Chart plotted by the subroutine described in the report, saving tedious and time-consuming manual plotting. Also included is a subroutine, ADMTPLT, which selects the data to be plotted on the Smith Chart. All control for the plotting of the charts and the data to be plotted is implemented in the main program. The effect of varying one parameter in the computation of data may be investigated by plotting more than one set of data on each chart. Appendix A shows the development of the algorithms for plotting the Smith Chart, and Appendix B shows the FORTRAN subroutine in a demonstration program. A sample plot is shown. (Author)
