Dispersion diagram for EBG in CST

Hi,

I'm trying to regenerate the dispersion diagram for an EBG as stated in the paper "Tailoring the AMC and EBG Characteristics of Periodic Metallic Arrays Printed on Grounded Dielectric Substrate"

Attached is a figure of the intended dispersion diagram taken from the paper, as well as my CST design file for the structure.

I've looked at some other older posts on the topic but the answers aren't 100% complete.

I'm using the Eigenmode solver with boundaries and variable phase as stated in this post --> https://www.edaboard.com/thread123197.html

Waiting for your support.

Hi
Khaled did you find how to do it? plz let me know

That was long ago... but you can have a look at the following two posts I found in my history for help:

Let me know if you're still looking for more.

thank you Khaled
how can i plot frequency Vs wave vector.
i need a matlab code nn ??

No you can do that directly in CST using the template based post-processing if I remember well..

thank you
but i can't find it
