Arbitrary polarization and rotation multiplexed metasurface hologram.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Metasurface holograms, characterized by their ultra-small thickness, high efficiency, and low loss, hold significant potential for applications in optical information storage, optical field manipulation, and security encryption. This paper proposed a polarization switchable and rotation multiplexing metasurface based on simultaneous amplitude and phase modulation. By precisely designing meta-atoms, the geometric parameters and orientation angle are engineered to independently control the phase and amplitude distributions of the metasurface. Utilizing a polarization switching strategy, incident light with different polarization angles generates distinct holograms. Additionally, the rotation-multiplexing mechanism further enhances information storage capacity by rotating the metasurface disk, thereby increasing the diversity and degrees of freedom in hologram. The results demonstrate that this approach enables precise optical field manipulation across multiple degrees of freedom, facilitating the reconstruction of multichannel holograms. This method provides a novel technological pathway for high-density optical storage, information encryption, and dynamic optical display.
