ie3D circulator

Is there a way to simulate a circulator in Zeland's ie3D software? If so, how would go about doing such an awesome thing?

what about your ciculator?
Is it likely circular-monopole?
I would like to help you,but I don't under stand your question.
Can you give more detail?

:)

Here are two papers that I would be interested in simulating:

Ansoft/HFSS has a circulator simulation example. You might ask them for a copy. I found an old copy that may be of some use to you. (I know your question was about IE3D.)
