Hi Stevens and MPB users, Refering to the example "A line-defect waveguide in a 2d triangular lattice of dielectric rods (c.f. tri-rods.ctl), formed by a row of missing rods along the "x" direction".
1- Exactly how much periods and crystal stuffing should be introduced through supercells? 1- If the lowest band is "folded" supercell-y times. How to calculate the exact bands from these folded bands due to supercells. 2- In the example (define K' (lattice->reciprocal (vector3 0.5 0 0))) ; edge of Brillouin zone. (set! k-points (interpolate 4 (list Gamma K'))) calcuates the bandgaps only in the x- direction why not find the bandgaps in the irreducable brillouin zone. 3- Consider '90 degree rotated triangular lattice'. Can I use the same basis vectors as 'original triangular lattice'.
