Mueller Matrix
Use the Mueller Matrix node to define Mueller matrices for customized optical components. Add this node from the Optical Devices submenu when Intensity computation is set to Compute intensity, Compute intensity and power, Compute intensity in graded media, or Compute intensity and power in graded media in the physics interface Intensity Computation section. 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 Reference axis specification:
•
User defined (the default). Then enter coordinates for the Reference axis R (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 reference direction 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 choice, select Isotropic (the default), Diagonal, Symmetric, or Anisotropic from the list and then enter a value or expression for the Mueller matrix M in the matrix or field.
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.
