Brief Abstract:
Metamaterials, which are engineered on the nanoscale, exhibit properties not found in naturally occurring materials and are a key aspect of nanotechnology. They can manipulate electromagnetic waves in novel ways, leading to groundbreaking applications in various fields. As surface counterparts of metamaterials, metasurfaces can tune the amplitude and phase of incident wavefronts by adjusting the layout of their subwavelength components: the meta-atoms. Metasurfaces are promising to replace conventional bulky wavefront control devices with high design flexibility and compact sizes. Their potential applications span from advanced imaging systems to next-generation communication technologies, making them a critical area of research and development.

This proposal outlines the integration of deep learning with metasurface design and optimization, aiming to enhance optical engineering through advanced computational techniques. First, a brief background on metasurfaces and metasurface design methodology is presented. Second, the challenges of metasurface design and the implementation of deep learning to assist metasurface design are addressed. Third, the development of phase change material-based metasurface design is introduced. Lastly the use of deep learning algorithms to optimize optical metasurfaces and wide-field-of-view optical metasurfaces imaging are discussed.
