GTK2 program for antenna simulation and analysis
Xnec2c is a GTK2-based Graphical version of nec2c, a translation to the C language of NEC2, the FORTRAN Numerical Electromagnetics Code commonly used for antenna simulation and analysis. The original nec2c is a non-interactive command-line application that reads standard NEC2 input files and produces an output file with data requested by "commands" in the input file. In contrast xnec2c is a GUI interactive application that (in its current form) reads NEC2 input files but presents output data in graphical form, e.g. as wire frame drawings of the radiation pattern or near E/H field, graphs of maximum gain, input impedance, vswr etc against frequency and simple rendering of the antenna structure including color code representation of currents or charge densities.
