The Orthogonal Polarization port
is available in 3D and 2D. When the
Type of Port is set to
Periodic under
Port Properties, this subnode is available from the context menu (right-click the
Port parent node) or from the
Physics toolbar,
Attributes menu.
Use the Orthogonal Polarization port to define port with a mode that is orthogonal to the mode of the parent
Periodic Port. Normally a
Orthogonal Polarization node is added automatically during the
Periodic port setup, but the
Orthogonal Polarization port subnode is also available from the context menu (right-click the parent node) or from the
Physics toolbar,
Attributes menu. Only one
Orthogonal Polarization node can be added per parent
Periodic Port.
Enter a unique Port name. Only nonnegative integer numbers can be used as
Port name as it is used to define the elements of the S-parameter matrix and numeric port names are also required for port sweeps and Touchstone file export.
The Orthogonal Polarization port is a listener port feature.
The Orthogonal Polarization port represent a zero-order mode (same as assumed for the parent Periodic port). Thus, the
Diffraction order settings are just for information and cannot be edited.
Enter a value or expression for the Mode phase θin (SI unit: rad). The default is 0 radians. The
Mode phase setting is further discussed for the
Port feature.
