Near Field Coupling between Maxwell and HFSS

The purpose of this coupling is to allow Maxwell 3D frequency domain solution magnetic fields to be used as a near field source in the coupled HFSS design at exactly matched frequency.

The suggested sequence of steps to create the link between Maxwell and HFSS is as follows.

1. Create and solve the Maxwell 3D frequency domain application at the chosen frequency.
2. Create the HFSS model.
3. Add "mapping" object to HFSS model.
4. Select all faces of the mapping object and apply a radiation boundary:

• check the Advanced Options check box.
• select the Enforced field radio button.

5. Click HFSS > Excitations > Assign > Incident Wave > Near Field Wave.

The Incident Wave wizard appears. In the wizard:

• Enter a name for the source or accept the default name and click Next;
• In the Incident Wave Source: Near Field Wave Options dialog:

1. Leave the translation and rotation data fields at their default zeros if the objects in the coupled designs have the desired location / orientation or change the values as needed.
Note: You can change the location of the source design origin and orientation (rotation) to perform different HFSS simulations without re-solving the Maxwell design.
2. Click the Setup Link button to specify the location of the source, Maxwell design.
3. Select OK to exit the Setup Link dialog.
4. Select Finish to finalize the Near Field link setup.
