Metasurface dispersion engineering for wavelength-insensitive directional photodetection.
Article in Optics letters, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Recent work has established the promise of tailoring the angular response of photodetectors through the integration of gradient metasurfaces on their illumination window for multiple applications in computational imaging. These metasurfaces function as reciprocal-space filters enabling the selective detection of light incident along a small, geometrically tunable set of directions. Here, we describe their development for wavelength-insensitive operation. The key outcome is a near-infrared device featuring a sharp peak in its measured angular response with minimal variations in center angle (<1° standard deviation) and peak value (<1.5 dB) across a bandwidth of 150 nm, nearly 3 times broader than in previously reported metasurface directional photodetectors. These results demonstrate the suitability of this device technology for applications involving LED light or even natural illumination combined with broadband spectral filters.
