AW Card
The AW card is a two line card which is used to define a waveguide port excitation. With this card a waveguide port excitation by an impressed mode on a rectangular, circular, or coaxial waveguide, can be modelled or the impressed travelling modes in all waveguides of a multi-port network can be imported from a .fim file.
On the Source/Load tab, in the Sources on
geometry group, click the Waveguide source (AW) icon.
