hfss ebg simulation
I am trying to use HFSS for simulating a Sievenpiper type of high impedance surface. I want to obtain the dispersion diagram.
1)how far away I should put the PML from the object (top patch). does it still need lamda/4 requirement as radiation boundary? what is the criterion for PML setting: (a) PML uniform layer thickness (b) minimus radiating distance
2)is it necessary for the PBC boundaries to cover the sides of the PML material on the top as well?
3)when I use Eigensolver, I get both real (almost real) eigen frequencies and complex eigen frequencies. How can I get the diesperion diagram out of this? I mean, what are those complex eigenfrequencies?
I try to simulate the structure of Sievenpiper paper:IEEE Tran. on MTT V47(11): 2059-2074. the structur parameters as page 2065, Fig.9,but I can't get the same answer as Fig. 10. I attach my design file, if possible could anyone tell me what is wrong for my design? If you get the right answer, could you send me the design file.
Thanks a lot!
