The band structures of square lattice photonic crystal and hexagonallattice photonic crystal have been computed in the second chapter.
在前人研究的基础上,我们对二维正方晶格和六方晶格光子晶体缺陷的带结构进行了计算。

Transmission electron microscopy (TEM) and high resolution electron microscopy (HREM) indicate that nano crystalline diamonds have hexagonallattice and cubic lattice.
