construction of disperstion diagram with HFSS

Hello,
I just start using HFSS. I try to construct the dispersion diagram of sievenpiper?s structure and I need help to do this. Can somebody help me how to do this.
Best regards

Which version of HFSS are you running? If you do a search in this forum you will find several postings that discuss generating the dispersion diagram of the Sievenpiper structure using HFSS. In my own experience the eigenmode solver of HFSS is not very efficent for analyzing the Sievenpiper structure especially in the fast-wave region. Others have recommended CST microwave studio, but no one has posted an example CST eigenmode project.

I use HFSS V 9.1, and I haven't CST microwave studio.
Thanks
