Moire Metamaterials and Metasurfaces

Optical metamaterials and metasurfaces enable versatile light manipulations. Advancements in modeling, nanofabrication, and characterization tools have led to the development of metamaterials and metasurfaces for many applications: energy conversion, biomedicine, and information technology. Recently, metamaterials and metasurfaces with moire configurations have attracted strong interest due to their highly tunable optical responses and high-throughput fabrication. Herein, state-of-the-art moire metamaterials and metasurfaces are reviewed. The presentation covers fabrication techniques, structure-property relationships, and applications in lasing and biomedical sensing. The review concludes with challenges and opportunities for moire metamaterials and metasurfaces.
