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. Define a variable.
   • d = 1 (Length of the cuboid.)
2. Create a cuboid.
   • Definition method: Base centre, width, depth, height
   • Base centre (C): (0, 0, -d/2)
   • Width (W): d
   • Depth (D): d
   • Height (H): d
3. Add a single incident plane wave with θ=75° and ϕ=45°.
4. Set the frequency span between 2.5 MHz to 300 MHz using a list of discrete points.
   1. Import the list of discrete frequency points from the file frequency_list.txt.
5. Specify the symmetry about the 3 principal planes.
   • X=0: Geometric symmetry
   • Y=0: Geometric symmetry
   • Z=0: Geometric symmetry
   Tip: Exploit model symmetries (if it exists) in a large or complex model to reduce computational costs.
