Polarization
Create a polarization plot to visualize the polarization state for diffraction orders, simulated for periodic structures.
The Polarization plot requires a license for the RF Module or Wave Optics Module.
Syntax
model.result(<pgtag>).create(<ftag>,"Polarization");
model.result(<pgtag>).feature(<ftag>).selection(...);
model.result(<pgtag>).feature(<ftag>).set(property, <value>);
model.result(<pgtag>).feature(<ftag>).run();
Description
model.result(<pgtag>).create(<ftag>,"Polarization") creates a polarization plot feature named <ftag> belonging to the plot group <pgtag>.
A polarization plot is used to visualize the polarization state using polarization ellipses. Polarization plots can be added to 1D plot groups.
The following properties are available:

Description
centerpos
auto | user
auto
The center position for the polarization ellipses. If set to user, enter the center position’s components using the xcenter and ycenter properties.
customlinecolor
RGB-triplet
{0,0,1} or last used edgecolor.

data

parent
The dataset this feature refers to.
differential
on | off

linecolor
custom | cycle | black | blue | cyan | gray | green | magenta | red | white | yellow
cycle
How to color the lines in the graph. Cycle indicates that the colors is different for each line.
linewidth
double
0.5
The line width.
linemarker

none
The line markers, if any. Cycle indicates that the marker is different for each line.
looplevel
integer row matrix
All solutions on all levels
The solutions to use, per level.
looplevelindices
integer row matrix
Empty
An alternative way to specify the solutions to use, allowing you to enter, for example, range(1,1,20). Applicable when looplevelinput is manualindices on a level.
looplevelinput
String array with all | first | last | manual | manualindices | interp on each level
all on all levels
How to input the solution to use, per level. manual on a level indicates that looplevel is used on that level. manualindices on a level indicates that looplevelindices is used on that level. interp on a level indicates that interp is used on that level.
markerpos
interp | datapoints
interp
Controls whether the positions of the markers are in the data points of the plot, or interpolated depending on the number (set in markers). Markers are visible when linemarker is set.
markers
integer
8
The number of markers to show. Markers are visible when linemarker is set.
linestyle
none | cycle | solid | dotted | dashed | dashdot
solid
The line style, if any. Cycle indicates that the line style is different for each line.
outerinput
all | first | last | manual | manualindices
all
How to input the outer solutions to use. Applicable only for parametric sweep models. manual indicates that outersolnum is used. manualindices indicates that outersolnumindices is used.
outersolnum
nonnegative integer array
1
The index of the outer solutions to use. Applicable only for parametric sweep models. Since the various outer solutions can have different number of solnum, the solnum property is not used.
outersolnumindices
String or integer array
Empty
An alternative way to specify the outer solutions to use, allowing you to enter, for example, range(1,1,20). Applicable when outerinput is manualindices.
scale
double
1
The scaling of the polarization ellipses.
showrotdir
true | false
true
Whether to show the direction of rotation.
solnum
integer array
All solutions
The solutions to plot. Available when data is not parent and the underlying data has multiple solutions.
solnumindices
String or integer array
Empty
An alternative way to specify the solutions to use, allowing you to enter, for example, range(1,1,20). Applicable when innerinput is manualindices.
solrepresentation
