I need to apply Floquet periodicity to a Hexagonal array of dielectric rods in an another dielectric matrix and calculate mode field distribution at a particular k-point of Brillouin zone for a particular frequency. Can you tell me how should I apply that boundary condition so that I can use my desired k-point at ease.

Thanking you...

The floquet boundary conditions are used in the Wave optics module -> Gratings and Metamaterials -> plasmonic wire grating example in the Model Libraries. You can see in that example how it is used. Only now you have to put three 'Periodic Condition' nodes, one for every pair of opposing faces. Also in this example they have used the 'copy edge' node in the mesh settings to make sure that the meshing of the opposing faces is equal, I am not sure if this is important.
