Filling Bloch Boundary Region with Materials
Hello, I'm currently trying to simulate the power absorbed by the photonic crystal. To do so, I have implemented a bloch boundary condition but I cannot determine whether should I fill the Bloch boundary region(blue area) as in the left figure, or should I leave it empty. It might seem as a minor difference, but simulation result shows dramatic difference.
I have applied the PML boundary condition to the top and the bottom boundaries, with 'extend structure through PML' option enabled. I even put some extra material above just in case, so I think the PML is not the one making the trouble.
