Metamaterials are artificially structured composites engineered to exhibit electromagnetic responses unattainable in natural materials. Over the past two decades, metamaterials have enabled unprecedented control of light through phenomena such as negative refraction, artificial magnetism, and subwavelength waveguiding. This review provides a comprehensive survey of recent progress in optical metamaterials, focusing on their design principles, fabrication advances, and applications in lenses, cloaking, sensing, and integrated photonics. Emphasis is placed on developments in visible and nearinfrared regimes, active tunability, topological photonics, and metasurface platforms. Challenges including material losses, scalability, and integration with existing photonic systems are outlined, alongside prospects for future research toward practical optical metamaterial technologies.
