A scheme of graphical display of the distribution of electromagnetic field in waveguides based on MATLAB is proposed. The impacts of the distribution of electromagnetic fields in the same waveguides and different modes, waveguide size as well as the boundary conditions on the result of simulation are discussed. Experiment results provide guidance for the curriculum.)
