== Running a Parametric Sweep of the Elevation Plane Wave Incident Angle ==
In this part of this tutorial lesson, you will vary the theta incident angle of the plane wave source and see how it affects the RCS of your target. As the previous part of this lesson, use a TE-polarized plane wave source to illuminate your target. In a sweep simulation, one or more parameters are varied, and the simulation engine is run for each parameter set. Open the Simulation Run dialog and choose the '''Parametric Sweep''' option from the '''Simulation Mode''' drop-down list. Click on the {{key|Settings}} button next to this drop-down list to open the Parametric Sweep Settings dialog.
