Damn ! Ok so what is the solution then to have a periodic structure in 2 directions only ? Is it correct to set k-point and then put a pml-layers in the direction where we don't want periodicity ? For example I want periodicity in X and Y only, so I do: (set! k-point (vector3 0 0 0)) (set! ensure-periodicity true) (set! pml-layers (list (make pml (direction Z) (thickness 1.0)))) Is there a more proper way ?
