Sweeping Values Across a Sphere

1. Set up a near-field sphere or a far-field infinite sphere.
2. In the Report dialog box, click the sphere geometry of interest in the Geometry list.
3. For the Sweeps variable corresponding to phi, select the ellipsis [...] button.

This displays a small dialog.

4. Clear the Use all values check box to enable selection and editing of the sweep values.

All of the possible values for the phi variable are listed in the dialog box. The values are the result of the range of phi you specified during the infinite sphere's setup. To modify the values of phi to be plotted across the sphere, do the following:

1. Click Edit Sweep.
2. Specify the following information:
   

   Step or Count	Whether to sweep by steps, or by linear count, decade count, octave count, or exponential count.
   Start Value	The point where the rotation of phi begins.
   End Value	The point where the rotation of phi ends.
   Step or Count	The number of values between the start value and the end value.

   
   
3. Click Update Values, and then click OK.

The values listed are updated to reflect the new number of points.

5. To plot the selected quantity or quantities at every value of phi, select All Values.

To plot the selected quantity or quantities at specific values of phi, clear the All Values option, and then select the phi values at which you want to plot.

6. For the Sweeps variable corresponding to theta, follow steps 4 and 5 for modifying the values of theta, if necessary, and specifying the theta values at which to plot the selected quantity or quantities.
   Note:

   All antenna parameters and maximum far-field data calculated by HFSS is at their maximum over the selected object; if you plot the parameter over a sweep of values, the parameter will have the same value at each point on the plot.
