offset-parabolic reflector directivity

Hi....

I want to simulate offset-parabolic reflector in hfss v9 i have need to know what the relation between (directivity, gain, beam width ) and parabola focal length and its diameter.

I think you can't simulate a reflector in HFSS 9. GRASP is usually used for reflector simulation.

You could also try FEKO.
