The review article focuses on how artificial intelligence (AI) is providing solutions for optical metasurface technology to transition from unit-cell optimization to system-level integration, overcoming key design challenges.
AI is important because it addresses challenges at each design stage, shifting metasurface design from traditional, staged methods toward intelligent, collaborative, and system-level optimization, which enables advanced applications.
At the unit-cell level, AI-driven surrogate modeling accelerates electromagnetic response prediction, inverse design frameworks explore complex solution spaces, and robust design methods enhance stability against manufacturing variations.
The review mentions AI methods including graph neural networks to model non-local interactions between meta-atoms, multi-task learning to resolve conflicting performance objectives, and reinforcement learning to enable real-time dynamic control.
At the system level, AI provides a unified differentiable framework that integrates structural design, physical propagation models, and task-specific loss functions, enabling end-to-end optimization that directly links nanostructure design to final application goals.
