A MATLAB-Based Virtual Tool for Simulations of Wave Propagation Inside a Parallel-Plate Waveguide [Testing Ourselves]

A MATLAB-based propagation tool called plate graphical user interface (PlateGUI), which calculates and shows electromagnetic (EM) fields inside a parallel-plate waveguide using different analytical and numerical models, was developed and is discussed in this article. PlateGUI can be used in graduate-level courses that deal with guided-wave theory and computational electromagnetics (CEM).
