摘　　要：运用平面波展开法模拟计算了二维六边形晶格光子晶体的能带结构,得到了使光子带隙最大化的结构参数.分别以不同介质作为本底,由圆柱、正方直柱和六角形直柱空气孔构成的六边形晶格光子晶体都出现了完全光子带隙,为进一步光子晶体的实验制备和应用提供了理论依据.The plane-wave expansion method is used to calculate the band structure of a two-dimensional photonic crystal with hexagonal lattice, and the optium structural parameters of photonic crystals with the largest complete bandgap are obtained. Different materials have been used as background, and the photonic crystals of hexagonal lattice with circular, square and hexagonal air columns all display complete photonic band gaps, which may then serves as guidelines for experimental preparation and application of photonic crystals.
