Hi,
To find Gap-Map, using FDTD, for square lattice of dielectric coulumns in air, I choose the 'X' position in reciprocal lattice, while varying the radius of the rods. The result is good.
But while considering the triangular lattice, I am a bit confused to choose the point in reciprocal lattice. Is it the 'M' or 'K'. Where the gap opens?
