Implementation of complete two-dimensional bandgap in photonic crystals of square Bravais lattice using complex unit cell

利用复式晶胞实现二维正方形布拉菲格子光子晶体的完全带隙

With a hard-wall square boundary, the Wigner crystal lattice is square as the number of particles N < 66, but becomes a hexagon as N ≥ 66 since the boundary effect is weak for inner particles.
