How to create a Curved FSS Radome structure using CST MWS?

here are the steps on how to create a Curved FSS Radome structure using CST MWS:

1. Define the radome geometry

Open CST MWS and start a new project.
In the Design Manager, go to Objects > CAD > Mesh and select "Extrude".
In the Extrude window, define the shape of the radome base. For a simple curved radome, you can use a circle or ellipse.
Specify the thickness of the radome wall.
Optionally, you can add fillets or chamfers to the edges of the base for a smoother transition to the curved radome section.

2. Create the curved radome section

In the Design Manager, go to Objects > CAD > Mesh and select "Revolution".
In the Revolution window, select the radome base as the "Object to Revolve".
Define the axis of revolution by selecting two points or lines. The axis should pass through the center of the base and be perpendicular to the base plane.
Specify the angle of revolution. For a full dome, the angle should be 180 degrees.
Optionally, you can add fillets or chamfers to the edges of the curved section.

3. Add the FSS layer

In the Design Manager, go to Objects > Sheet and select "Metal".
Define the shape and thickness of the FSS layer. The FSS layer can be placed inside or outside the radome wall.
If the FSS layer is inside the radome wall, you will need to create a cutout in the radome wall to accommodate the FSS layer.

4. Define the material properties

In the Material Manager, define the material properties of the radome wall and the FSS layer. You will need to specify the permittivity, permeability, and conductivity of each material.

5. Set up the simulation

6. Run the simulation

Once you are satisfied with your model setup, click the "Run" button in the Solver Manager.
CST MWS will calculate the S-parameters and other electromagnetic properties of the radome structure.

7. Analyze the results

Once the simulation is complete, you can view the results in the Postprocessing window.
You can plot the S-parameters, the transmission and reflection coefficients, and the field distributions inside and outside the radome.

Here are some additional tips for creating a Curved FSS Radome structure using CST MWS:

Use symmetry planes to reduce the simulation time if your radome is symmetrical.
Use parametric sweeps to optimize the design of your radome.
Use the built-in CAD tools in CST MWS to create complex radome shapes.
There are many online resources and tutorials available for using CST MWS to design radome structures.
