Recent breakthroughs in deep learning have introduced an essential tool for optics and photonics, with applications in material design, system optimization, and automation control. Deep learning-enabled on-demand metasurface design overcomes the shortcomings of conventional simulations and physics-based methods. Inspired by object-oriented programming, a knowledge-inherited paradigm for multi-object and shape-unbound metasurface inverse design is proposed. By benchmarking the paradigm, a 86.7% accuracy is achieved in the free design of aperiodic and periodic metasurfaces. Additionally, an intelligent origami metasurface is presented to enhance satellite communication facilities.
Recent breakthroughs in deep learning have ushered in an essential tool for optics and photonics, recurring in various applications of material design, system optimization, and automation control. Deep learning-enabled on-demand metasurface design has been the subject of extensive expansion, as it can alleviate the time-consuming, low-efficiency, and experience-orientated shortcomings in conventional numerical simulations and physics-based methods. However, collecting samples and training neural networks are fundamentally confined to predefined individual metamaterials and tend to fail for large problem sizes. Inspired by object-oriented C++ programming, we propose a knowledge-inherited paradigm for multi-object and shape-unbound metasurface inverse design. Each inherited neural network carries knowledge from the parent metasurface and then is freely assembled to construct the offspring metasurface; such a process is as simple as building a container-type house. We benchmark the paradigm by the free design of aperiodic and periodic metasurfaces, with accuracies that reach 86.7%. Furthermore, we present an intelligent origami metasurface to facilitate compatible and lightweight satellite communication facilities. Our work opens up a new avenue for automatic metasurface design and leverages the assemblability to broaden the adaptability of intelligent metadevices.
