Cassegrain modeling in feko

Hi everybody,

I'm working with the cassegrain antenna and i have trouble modeling it in feko. I wonder if any one can guide me to how exactly to model and run the cassegrain antenna in feko.

In short, i modeled it in feko environment as three parts feed, sub reflector and main reflector. To run it, i feed the sub reflector with the near field of the feed and the same thing for the main but by the near field of the sub. Is this right or is there any other way to model and run the cassegrain in feko.

Looking forward for your replies..

You can do that, is it because of memory limitations on your machine?

You can also just replace the feed with a near field and model the rest with ray-launching GO. Of course, if your machine has enough memory MLFMM is always first prize.
