How to measure permeability at THz using HFSS?

I was trying to redo a simulation that I read in a article. It is about measuring permeability of a metamaterial. I have finished the model same as the sample D1 described in the article using HFSS 10. But I don't know how to set up the excitation and boundary, and how to measure the permeability. Specifically, I want to create a graph of the imagninary and real part of the permeability of the metamaterial as done in figure 3 in the attached article. Can anyone show me how to complete the measurement of the permeability? Thank you very much.

Hi,

Could you do that then ??

I like to do the same using MW CST. Could you please advise me ??

Regards

I also want to learn something and could you tell me whether HFSS is aviable to simulate metamaterial. If it is okey, could you give me some advice how I can start with HFSS.

Thanks very much!
