Polarization

) plot to visualize the polarization state for diffraction orders, simulated for periodic structures. A polarization plot displays polarization ellipses for the different diffraction orders in the same diagram. Add a Color Expression subnode as needed. Right-click a to add this plot from the submenu.

	This plot is available with the RF Module or the Wave Optics Module.

From the list, choose a predefined expression, if available, or choose or . If you chose , enter expressions for the polarization plot in the and fields. There can also be other predefined options such as when you have solved a Wavelength Domain study for an Electromagnetic Wave, Frequency Domain interface, for example.

If desired, clear the check box, which is selected by default, to not display the direction of rotation as an arrow head on the polarization ellipses.

The default value in the field is 1. Use another value to scale the polarization ellipses.

From the list, choose (the default) to determine the center position of the polarization ellipses automatically. Choose User defined to enter center positions in the and fields.

The check box is selected by default to display the plotted expressions to the right of the plot. In plots where each line represents a certain time value, eigenvalue, or parameter value, these values are also displayed.

When is selected from the list (the default), select or clear the and check boxes to control what to include in the automatic legends (by default it includes the solution only). You can also add a prefix or a suffix to the automatic legend text in the and fields. If is selected from the list, enter your own legend text into the table. If is selected, you can use the eval function to create an evaluated legend text in the field that include evaluated global expressions such as global parameters used in sweeps. For the numerical evaluation, you can control the precision in the field (default: 3).
