Sources

These sources input energy into the simulation space.

Circuit Components
Specify the location of a lumped component.
Modal Waveguide Excitation
Excite a waveguide structure with TEM, quasi-TEM, TE, or TM modes.
Nodal Waveguide Excitation
Specify pins for exciting a transmission line.
Plane Wave Excitation
Define the incident direction and polarization.

Additional Waveguide Settings

Modal and nodal waveguide editors each include geometry and boundary tabs that have different explanations, meanings, and recommendations.

Waveguide Boundaries
