COMSOL 6.4 - Study 1

The remaining work is to vary the two design parameters to minimize reflections at the nominal frequency. To do this, perform parametric sweeps over the design parameters (scale factors).

Modify the study to vary the scale factor to determine the size of the ferrite post. The study type is still Frequency Domain.

Parametric Sweep

The parametric sweep over the scale factor is added as an extension to the frequency domain study.

1

In the Study toolbar click Parametric Sweep

2

Go to the Settings window for Parametric Sweep. Under Study Settings click Add

under the Parameter names table.

3

In the Parameter names list, select sc_ferrite (Geometry scale factor).

4

Under Study Settings click the Range

button. In the Range dialog:

-

In the Start text field, enter 0.5.

-

In the Step text field, enter 0.003.

-

In the Stop text field, enter 0.53.

Alternatively, enter range(0.5,0.003,0.53) in the Parameter value list.
