Dear all,
I'm trying to calculate the gap map of the hexagon structure in square
and triangular lattice.
It's OK to define the structure in square lattice by using overlapping
of three blocks:
(set! geometry (list
(make block (center 0) (material air)(size r c infinity
))
(make block (center 0) (material air)(size r c
infinity)(e1 0.5 (/(sqrt 3) -2) 0) (e2 (/(sqrt 3) 2) 0.5 0))
(make block (center 0) (material air)(size r c infinity
) (e1 0.5 (/(sqrt 3) 2) 0 ) (e2 (/(sqrt 3) -2) 0.5 0))))
But the pattern goes wrong when I use the same overlapping in
triangular lattice.What's the mistake did I make? How to define the hexagon
structure in a triangular lattice?
Thanks,
Mutian
