DOI: 10.1002/adom.202500224

Abstract: In this study, a phase of metasurface is proposed based on rotational ring configuration, whose tuning principle is associated with its conversion between spin angular and orbital momentum. The focusing vortex beams could be obtained… read more here.

DOI: 10.1088/1555-6611/ac31bb

Abstract: For a common metasurface with gradual phase, once the metasurface element structure is designed, we can only obtain a limited number of abnormal deflection angles based on the different arrangement characteristics of the metasurface element… read more here.

DOI: 10.1109/tmtt.2023.3328480

Abstract: In this article, a geometric-phase (GP) metasurface-inspired phase shifter with linear and continual phase response has been introduced. The output phase can be adjusted by only rotating the GP metasurface. Physically distinct from the traditional… read more here.

DOI: 10.1364/oe.461024

Abstract: Perfect vortex (PV) beam has seen significant advances in fields like particle manipulation, optical tweezers, and particle trapping, due to the fact that its ring radius is independent of the topological charge. Although geometric-phase metasurfaces… read more here.
