phase diagram in hfss!

[Abu Maria.]

hi!

I try to use HFSS for the phase diagram and dispersion of a cell mushroom like EBG , I am a beginner, but Imake an effort! Please, is there someone who can put the steps here clearly for the purpose, or a pdf that explains clearly and in detail how to get this diagram? I need this, so I expect from you as usual!

thank you very much!

please , i want to design this in hfss !

I've drawn this figure, and I'm stuck

I have a problem, how to insert the incident wave? and how to do the boundary conditions on the walls of the box?

thnx

hi u should master and slave for periodic structure
for this aim you can use slave port of hfss

Abu Maria,

For your first post, you must perform an eigenmode simulation. There are example of this type of simulation in the HFSS help files. You will need to employ master and slave boundaries to represent the infinitely periodic structure, as ferdows explained, however, you do not need any excitation types.

For your second post, you want to make the top surface of the vacuum box a wave port (of course, you still want master/slave boundaries on the sides). Then, get the S-Parameters, and the curve shown in the diagram is simply the phase of S11.

Good Luck
