Creating the Model

Create the model in CADFEKO. Define any ports and sources required for the model. Specify the operating frequency or frequency range for the model.

1. Use the model considered in MoM Horn and LE-PO Reflector and rename the file.
2. Set the solver method for the reflector face to use PO - always illuminated method.
   Tip: Open the Face properties dialog and click the Solution tab. From the Solve with special solution method list, select Physical optics (PO) - always illuminated.
3. Solve the model with the MLFMM solver.
   Tip: Open the Solver settings dialog, click the MLFMM / ACA tab and then click Solve model with the multilevel fast multipole method (MLFMM).
4. Couple the MLFMM and PO.
   Tip: Open the Solver settings dialog, click the High frequency tab and then click Couple PO and MoM/MLFMM solutions (iterative technique).
