Create the model in CADFEKO.
Define any ports and sources required for the model. Specify the operating frequency or
frequency range for the model.
-
Define the following variables:
- lambda = 4 (The wavelength in free space.)
- freq =
c0/lambda (The operating frequency.)
- h = lambda/2 (Length of the dipole.)
- radius = 2E-3 (Radius of the wire.)
-
Create the dipole.
-
Create a line.
- Start point: (0, 0,
-h/2)
- End point: (0, 0,
h/2)
-
Add a wire port (vertex) to the middle of the line.
-
Add a voltage source to the port. (1
V, 0°, 50 Ω).
-
Set the frequency to freq.
The model is symmetric about the Z=0 plane. The electric fields are normal to
this plane, and therefore the symmetry is electrical.
-
Specify the symmetry about the Z=0
plane as Electric symmetry.
Tip: Exploit model symmetries (if it exists) in a
large or complex model to reduce computational costs.
