Waveguide Ports

A waveguide port is used to define the planes of excitation for waveguide structures.

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:
  • the face must be flat
  • 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)
