Dispersion Diagram in CST

[Ahmad.Bayat]

I used an ohmic sheet in the structure from which I want to get
dispersion diagram. The problem is that CST says that it is impossible
to use eigenmode solver when ohmic sheet or surface impedance exist.
Also the results by varying the resistance and reactance are the same
without any bandgap.

I will be thankful if you help me to solve this problem.

Thanks.

hi ahamad

i had this problem too , for solving that :

you can use another method ,which by modifing a bulk or volume and choose the ohmic or another material for use .
now just solve time domain method .

i hop to be helpful
