Waveguide Ports
A waveguide port is used to define the planes of excitation for waveguide structures.
Note: Waveguide ports can be applied to:
- a single flat face solved using SEP.
- a single flat face on the boundary of a FEM region.
Three basic waveguide cross-sections are supported:
- Rectangular
- Circular
- Coaxial
Waveguide ports are specified on a single face with the correct shape. To apply a port to
a face, the following requirements must be met:
Figure 1. The waveguide port is indicated by a blue border. A waveguide port containing a waveguide source, is indicated by a red border.
- the face must be flat or a flat face on the boundary of a FEM region
- the face cannot contain any internal edges
- the face must form the boundary of a PEC or dielectric region
- the face cannot have any special material properties (for example, dielectric coating)
- the face cannot be solved with special solution methods (for example, UTD)
