Fields in shorted waveguide. A parallel plate waveguide operates in a TM mode and has the following electric and magnetic fields:
where Ac is the cutoff wavelength and λg is the guide wavelength. The wave propagates in the Z direction and the material in the waveguide is free space. Dimensions and coordinates are shown in Figure 17.26. Now, a perfect conducting plate is used to short the two parallel plates (dotted line). Calculate the electric and magnetic field intensities to the left of the short. Assume the short is at Z = 0 for simplicity.
