Ultrathin ring-shaped metasurface for a multiview 3D display

The development of glasses-free 3D multiview displays has opened up new avenues for experiencing 3D displays. Multiview technologies have the advantages of visual discomfort alleviation, smooth motion parallax, full-color display, and broad depth of focus. However, their intended uses are impeded due to the versatility of designing ultrathin display systems freely by using metasurface technology. This paper presents a technique for creating an ultrathin ring-shaped metasurface for a multiview display system with a thickness of 2 μm. The proposed multiview 3D display system generates eight views. Numerical simulations are used to confirm the efficacy of the suggested strategy, and the results demonstrate the attainment of a high-quality multiview 3D display. The proposed work demonstrates the potential applications of the metasurface in multiview display systems for electromagnetic wave manipulation in future 3D TVs, imaging, integrated optics, and next-generation compact displays.
