Waveguide Ports
A waveguide port is used to define the planes of excitation for waveguide structures.
Three basic waveguide cross-sections are supported:
- Rectangular waveguide
- Circular waveguide
- Coaxial waveguide
Waveguide ports are specified on a single face with the correct shape. To apply a port to
a face, the face must be flat, not contain any internal edges, form the boundary of a
PEC or dielectric region, not have any special material properties (for example,
dielectric coating) or be solved using special solution methods (for example, uniform theory of diffraction).
