Rectangular Waveguide |
wg.lcx The geometry is a rectangular waveguide, 1/3 lambda by 2/3 lambda, capped at one end. It is excited by a continuous sinusoid near the end.
Run the simulation for 500 time steps to get into steady-state, longer to watch the repeating pattern. Use a +Z viewport to watch the pulse train bounce down the waveguide. A +Y view will show the excitation at a slice at the opening of the structure. Three plots (e1, e2, and e3) show the signal at different points along the waveguide (e1 is plotted as the simulation runs).
