Cover Story: Artificial intelligence (AI) significantly enhances the development of Meta-Optics (MOs) and could complete sophisticated modeling and optimization to achieve precise control over light behavior. Machine learning (ML) algorithms can analyze extensive datasets and simulate numerous design variations to identify the most effective configurations, drastically speeding up the development process. AI also enables adaptive MOs that can dynamically adjust to changing imaging conditions, improving performance in real-time. The combination of AI with MOs thus epitomizes a transformative advancement, pushing the boundaries of what is possible in imaging technology. In this review, we explored the latest advancements in AI-powered metalenses for imaging applications. View this paper
