    Sir I want to ask that if we have a Cylindrical array both in X and Y axis Having point/Surface contact between them . Then how can we select the unit cell out of entire geometry to apply the periodic boundary condition. basically what is criteria to select unit cell ? in your case there is distance between two cell but in my case there is no gap. Please help me out.

      @@MVBMOHDSHADAB I don't know. I'm not experienced in metamaterials.

    If we replaced this geometry with perforated plate like structure then what Boundary condition do we need to apply at the empty surface. That's is my concern. Please help me out.

      It is a 3D crystal modeled in 2D and depth is not taken into account. You need to model the perforated plate in 3D.
