Creating 2D Polar Plots

In HFSS, a polar plot is a 2D circular chart divided by the spherical coordinates R and theta, where R is the radius, or distance from the origin, and theta is the angle from the x-axis. Following is the general procedure for drawing a polar graph of results:

1. On the Results menu (HFSS menu or right-click Results on the Project tree), click Create <type> Report, and select Polar Plot from the report type menu.

The Report dialog appears.

2. In the Context section make selections from the following field or fields, depending on the design and solution type.

1. Solution field with a drop down selection list. This lists the available solutions, whether sweeps or adaptive passes.
2. Domain field with a drop down selection list. Whether this field appears, and the domains listed depend on the Solution type and the <type> selected. For modal and terminal solution data reports, the domain can be Sweep or Time.

Before you can examine the time domain, you must perform an Interpolating sweep for a driven solution (Modal or Terminal). If you select Time, the TDR Options button is enabled. Select it and follow the directions for time-domain plotting.

3. Geometry field with a drop down selection list. For field and radiated field reports, this applies the quantity to a geometry or radiated field setup.

3. In the Trace tab PolarComponent area, specify the information to plot:

1. On the Category drop-down menu, click the type of information to plot.
2. On the Quantity list, click the values to plot. Use Ctrl+click to make multiple selections.
3. In the Function list, click the mathematical function to apply to the quantity for the plot.
4. The Value field displays the currently specified Quantity and Function. You can edit this field directly.
   Note:

   Color shows valid expression.

5. Range Function button -- opens the Set Range Function dialog box. This applies currently specified Quantity and Function.

4. Click New Report.

This creates a new report in Project tree, displays the report with the defined trace, and enables Add Trace on the Report dialog box. The default name is based on the Report Category you selected, (for example, S Parameter Plot n or rE Plot n). You can edit the plot names in the project tree and the plot header text in the report synchronizes.

The function of the selected quantity will be plotted against the swept variable values or quantities you specified on an x-y graph. The plot is listed under Results in the project tree and the traces are listed under the plot. When you select the traces or plots, their properties are displayed in the Properties window. These properties can be edited directly to modify the plot.

5. Optionally, add another trace to the plot by following the procedure above, using Add Trace rather than New Report.
