problem with split ring resonator

I wanted to simulate a split ring resonator in hfss (like this paper in attachment) but my results are not similar to result of paper.
both paper anf hfss file are in the attachment.
please help me

The picture of(CSRR)inside of waveguide?
please help me?

Yes,for sure its inside the waveguide.They put it inside and get the frequency for that dimension.If u wan additional dimension details that lead to the desired frequency..i can find it for u..

The simulation should compromise the simulation. For example the ari medium size, area of simulation....so on
