A space-time holographic metasurface antenna.
Article in Science advances, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
Holography is a revolutionary imaging technology capable of storing and recovering full-wave information of the light fields scattered by objects. However, current hologram configurations are based on space-only modulation and can merely record the amplitude and phase information of object lights. Here, we advance the holography concept by transitioning it from a space-only, homodyne, and single-tone approach to a spatiotemporal, heterodyne, and multifrequency methodology. We theoretically propose and experimentally demonstrate a space-time holographic metasurface antenna (HMA) capable of encoding and reconstructing the full amplitude, phase, and frequency contents of object waves. We demonstrate the HMA for frequency conversion and holographic beamforming in the far field, as well as multifrequency two-dimensional (2D) and 3D holographic imaging in the near field. The proposed integrative and multifunctional space-time HMA goes beyond the existing holography technology, with the potential to enable a plethora of applications such as augmented/virtual reality, data storage, metrology, and wireless communications.
