Calculation: A representation of a network of electromagnetic waveguides (left) being used to solve Dirichlet boundary value problems. The coloured diagrams at right represent the normalized instantaneous Hz-field values calculated at each of the junctions inside the waveguide network. (Courtesy: R.G. MacDonald, A. Yakovlev, and V.
