Reconstructive spectrometer using double-layer disordered metasurfaces.
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 3 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
Conventionally, optical spectrometers rely on traditional dispersive elements like grating and prism, which pose inherent challenges for miniaturizing spectrometers, including the trade-off between propagation distance and spectral resolution and calibration ambiguity. Here, we present a random dispersive element-double-layer disordered metasurfaces-where wavelength-specific speckle patterns can be uniquely determined a priori without ambiguity in wavelength and propagation distance. By directly mounting this element on an image sensor, we implement a spectrometer with a spectral resolution of around 1 nanometer and an operable range of 440 to 660 nanometers, comprising 221 spectral channels, within a form-factor of less than 1 centimeter. Our results firmly establish that the versatility of multilayer disordered metasurfaces in the spatio-spectral domain can be fully exploited for on-sensor spectroscopic applications.
