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

In two-dimensional photonic crystals of square Bravais lattice, complex unit cell was considered to achieve a complete bandgap- By adding an optimal algorithm in our calculation, the structure parameters of photonic crystals with the largest complete two-dimensional bandgap were obtained-
