摘要：Metasurfaces offer a unique combination of functionality and compactness in shaping optical wavefronts, outperforming traditional bulky geometric optics devices. However, designing meta-atoms to meet specific electromagnetic responses can be challenging and time-consuming due to the added complexity of freeform shapes and reconfigurable materials. In this presentation, we propose the use of deep neural networks to streamline the forward modeling and inverse design of meta-atoms with a large number of design degrees of freedom. The neural network frameworks are capable of generating a variety of designs for both freeform and reconfigurable metasurfaces, as demonstrated by several successful design examples.
