|Fifth Example—Wave normal to reflector, 1 mm wide gap, parallel polarization|
In this example the plane wave is polarized with the E field in the y direction, but it is otherwise identical to the third example. The magnitude of the E field is shown. Since this polarization cannot propagate down the gap in the -z direction, essentially all the power is scattered isotropically. The rms field strength of the incoming wave is 1 V/m.
