# MLFMM Horn and PO Reflector

Simulate the horn using MLFMM and the reflector using PO.

Simulate the horn using MLFMM and the reflector using PO.

**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.**Defining Calculation Requests**

Define the calculation requests in CADFEKO.**Meshing the Model**

Create the model mesh in CADFEKO using the correct settings. A mesh is a discretised representation of a geometry model or mesh model used for simulation in the Solver.**Validating the Model**

Run the computational electromagnetic (CEM) validate tool to perform basic validation on the CADFEKO model.**Running the Feko Solver**

Run the Solver to compute the calculation requests.
