Preface to the special topic: Optical metamaterials
超构材料(metamaterials)自21世纪初被提出以来, 已经经历了20年的发展, 目前, 它仍然是非常活跃的前沿领域. 超构材料的研究覆盖非常广泛, 涉及光、电磁波、太赫兹波、声波、热、力学和弹性波等. 超构材料的基本思想是, 利用人工结构单元作为人造原子, 来构造宏观连续的介质, 通过结构单元的设计, 来调控介质的材料参数, 实现对波的传播性质的控制. 最早的超构材料结构单元是1999年英国科学家John Pendry提出的金属开口环结构, 它可以与电磁场相互作用, 产生磁共振, 从而实现负磁导率系数. 后来, 人们又提出了很多其他的人工结构单元, 实现各种应用. 超构材料最早的应用是负折射材料, 后来又有零折射率材料、双

Influence of bias magnetic field direction on band structure of magnetic photonic crystal and its role in constructing topological edge states
Xiang Xi, Kang-Ping Ye, and Rui-Xin Wu
The topological transitions in two-dimensional photonic crystals (PCs) originate from the opening-closing-reopening of the bandgap, accompanied with the band order inversion. The topological bandgap in magnetic PC can be created by applying a bias magnetic field or deforming the geometry structure of the PC. In this pa
