Need help to simulate EBG structure in HFSS

Please help me to simulate EBG structure using HFSS, as attached file! Because I am newer for HFSS, so I don't know how to set two-layer PML on the top of the structure for simulation and I can't get the same results with results in this paper.
Everyone, who know about simulation EBG structure, Please hepl me.
Thank you so much!

Hi ferdows:
Thank you so much for your reply!
My problem is how to create 2-layer PML on the top surface of the airbox of the unit EBG cell (that shown in slide 18). Because I can't do it. If possible can you hepl me? Now I am using HFSS v.12.
