“…Metasurface, composed of arrays of subwavelength structures, has been widely applied in areas such as vector light generation 1, 2 , holographic [3][4][5] , imaging [6][7][8][9] , and information encryption [10][11][12] due to its compact nature and great ability. By adjusting the arrangement, size, and orientation angle of the structures on the metasurface, flexible wavefront modulation can be realized in the plane.…”

Catenary metasurface has been widely used in fields such as wild-angle imaging, spectral detection, and broadband absorbers, due to its advantages of high efficiency and broadband. In our previous studies, perfect wavefront control of catenary metasurface is achieved via field-driven optimization (FDO). However, the proposed method focuses solely on the performance of catenary metasurfaces at a specific wavelength. Here, considering the broadband and multifunctional of the catenary and catenary-like metasurfaces, multi-objectives FDO is proposed. With 30 iterations, the average diffraction efficiency of the catenary metasurface increases to ~96% at the wavelength of 9-13 μm. In addition, considering the functionality, the catenary and catenary-like metasurfaces are optimized with a pair of orthogonal polarized light incidences. The optimization process preserves the chiral nature of the catenary metasurface. After 30 iterations, the diffraction efficiency of the catenary metasurface is improved from 96.4% to 99.2%. For catenary-like metasurfaces, the diffraction efficiencies exceed 90% for both left-handed and right-handed elliptically polarized light incidences. Our work provides a methodology for designing multifunctional complex continuous metasurfaces, which may further promote catenary optics.

VR devices have existential experiences that can meet the deeper interaction needs of humans and are the driving force behind the rapid development of the industry. As the latest computing platform, VR is facing unprecedented opportunities and challenges. In recent years, the continuous iteration of hardware to ensure the visual experience effect, system‐level interaction features more rich, game content developers continue to launch more high‐quality content, this series of industry progress to promote the VR ecosystem continues to improve, and continue to develop. At this stage, VR market participants are mainly divided into three camps: VR industry advocators, Internet content platforms, intelligent device terminal brands, etc., and the leading players continue to invest in the layout, and the future will show a highly concentrated trend. The combination of hardware and content roles strengthens the synergistic effect of both sides and preempts the core link of the meta‐universe.
