Create the model in CADFEKO.
Define any ports and sources required for the model. Specify the operating frequency or
frequency range for the model.
The model consists of a circular cylinder. The cylinder height is set to half a
wavelength at the excitation frequency.
-
Define the following variables:
- lambda = 1 (The wavelength in free space.)
- freq =
c0/lambda (The frequency for free space wavelength.)
- h = lambda/2 (The height of the
cylinder.)
- r = 0.1 (The radius of the infinite cylinder.)
-
Create a cylinder.
- Definition method: Base centre,
radius, height
- Base centre: (0, 0, -h/2)
- Radius: r
- Height: h
-
Delete the top and bottom faces of the cylinder.
-
Add a single incident plane wave with θ=90° and ϕ=180°.
-
Set the frequency to the variable freq.
