[SI-LIST] Simulation of Frequebcy Selective (FSS) and Periodic (PS) Structures in HFSS

Dear colleagues, 
 
I am working on Electromagnetic Band Gaps structures(EBG). I am trying to use 
Ansoft HFSS V.9.1 for modeling the scattering from 2-D EBG (by using the 
periodic boundary condition, master-slave, for our simulations). I have 
attempted a lot to obtain exact results by HFSS for PHASE of reflection 
coefficient. In fact, my results are satisfactory in case of perpendicular 
(theta=0) incident wave, but as the angle increases (oblique incidence) the 
results start to show more errors. I have surveyed all available points and 
resources, e.g. "Ansoft product training workshops", to solve the problem but 
non prevailed. 
 
I will appreciate if someone mind making some suggestions or introducing some 
helpful resources or clues.
 
Best regards,
Mehdi Hosseini
