Creating the Model
Set up the model to write the transmission / reflection coefficients .tr file to be used for the characterised surface.
- Use the model created in Periodic Boundary Conditions for FSS Characterisation and rename the file.
- Specify the symmetry about the X=0 and Y=0 planes as Geometric symmetry.
- Set the frequency to 10 GHz.
-
Modify the plane wave source settings:
- Click Loop over multiple directions.
- Set the θ range from 0 to 180°.
- Set the ϕ range from 0 to 360°.
- Increment the incident angle, θ, in 6° steps.
- Increment the incident angle, ϕ, in 6° steps.
- Select the Calculate orthogonal polarisations check box.
Tip: Use a single theta cut for elements with small / no variation in ϕ.Tip: For many θ and ϕ samples use the provided .tr file to save time.
