I would like to know if FEKO and HFSS give the same results for a horn illuminating a parabolic reflector, in the Ku-Band ?
Is there somebody who has already such a design with these tools ?
I have played with FEKO a two years ago, it is very good for large structures.
It is hybrid method, so I do not believe that there would be many people using it.
The best thing for you is to make a model using some examples from the literature (e.g. Belanis) and compare results.
