Linear Wave Retarder
Use the Linear Wave Retarder node to define a linear wave retarder on a boundary selection. Add this node from the Optical Devices submenu when ray intensity or power is solved for in the model. The Accumulator (Boundary) subnode is available from the context menu (right-click the parent node) or from the Physics toolbar, Attributes menu.
Device Properties
Select a Fast axis specification:
•
User defined (the default). Then enter coordinates for the Fast axis F (dimensionless).
•
Parallel to reference edge (for 3D components). The Reference Edge Selection section is then shown. Add an edge to this selection to specify the fast axis orientation. Only a single edge may be selected. The edge must be adjacent to a boundary in the physics feature selection.
•
In-plane or Out-of-plane (for 2D and 2D axisymmetric components)
For any selection, enter a value for the Retardance δ (SI unit: rad).
New Value of Auxiliary Dependent Variables
This section is available if an Auxiliary Dependent Variable has been added to the model. The settings are the same as for the Wall feature.
