摘要: Chiral metamaterials have attracted strong interest due to their versatile capabilities in spin-dependent light manipulation. Benefiting from advancements nanofabrication and mechanistic understanding of chiroptical effects, chiral shown potential a variety applications including circular polarizers, sensors, detectors. Recently, made by moire stacking, superimposing two or more periodic patterns with different lattice constants relative spatial displacement, promise for applications. The (MCMs) take advantage lattice-dependent chirality, giving cost-effective fabrication, flexible tunability, reconfigurability superior conventional metamaterials. This feature article focuses on recent progress MCMs. We discuss optical mechanisms, structural design, the conclude our perspectives future opportunities
