The structure is the EBG glide-symmetric unit cell, I only get the dispersion diagram of the glide-symmetric unit cell. How can I get the attenuation result like the picture?
Thanks!

In a simulator, you probably need to simulate the scattering of a finite cascade of unit cells and extract the effective attenuation constant from the scattering parameters.
