Optimise Waveguide Pin Feed Location
Analyse the effect of the pin offset on the reflection coefficient using an optimisation grid search and the NGF solution settings.
A waveguide can be fed using a pin placed at a quarter of a
waveguide wavelength from a terminated waveguide end. For an arbitrary cross-sectioned
waveguide, the waveguide wavelength is not always known making it difficult to determine
the pin feed position.
