Dear Steven and MPB's users,
You suggest me that my computation cell is wrong. When I calculate the waveguide, I need to have only "one" unit cell along the direction of the waveguide and a supercell only in the transverse directions.
My calculation is finding the waveguide in PC slab (triangular lattice of air holes):
I refer to the example "line defect waveguide in a 2D triangular lattice of dielectric rods" in MPB's Tutorial. I used this command:
(geometric-objects-lattice-duplicates geometry)
to duplicate the bulk crystal holes over the supercell.
And then, the bulk crystal holes are over all 3D (I look at in the result.out file). But I need only to have 2D (x and y directions). What can I do this calculation? Could you help me!
I thank you in advance,
Nils Jensen
