metamaterials simulation cst

Hi,
Any Guys can give some suggestion , CST and HFSS which is better for simulation of metamaterials.

Thanks very much.

PS:
As well as how about COMSOL?

Hi
If u just talk about the accuracy of the results, then except mos tof the research groups are using

1) HFSS (Accurate but tooo slow used by itol and many other groups)
2) COMSOL (Accurate and used especially for cloaking currenlty all papers by smith group are using COMSOL). In my opinion COMSOL is going to overcome metamaterial simulation market due to its enhaced functionality but difficult to start with
3) CST (good enough used by Jiu A KONG

I don't think Jin A. Kong would run the simulation himself. Even if he does so, that doesn't mean CST is "Good Enough". These professors might know a lot about metamaterial, but...

Dear loucy

I did not mean like and sorry if it mislead any body. What i meant to say is differnt research groups are using differnts software as mention in case of smith and itol (accodring to the paper that i read) and i am quite sure they also never used them but they are big in the area. Well kong is big man smith and itol has much contirubiton regarding the metamaterials

Regards
