Full polarization and high coherence control of thermal emissions via saddle-band dispersion engineering.
Article in Nature communications, 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
Photonic engineering in metasurfaces has enabled unprecedented control over thermal emissions in recent years. Here, we present a design strategy that achieves full and simultaneous control over both polarization and coherence of thermal emission across a broad range of output angles. Our design builds upon a double-sided corrugated waveguide array that supports a unique saddle-shaped high-Q dispersion band-parabolic along the waveguide direction to ensure high spatial coherence by involving minimal wavevectors, and flat in the perpendicular direction to enhance collection efficiency through 1D spatial filters and focusing lenses. The continuous tuning of polarization states is achieved by adjusting the relative offset of corrugations along the waveguide direction. We fabricate a series of metasurfaces and demonstrate record-high temporal coherence (Q ≈ 304), spatial coherence (coherence length: 0.32 mm), spin coherence (emission circular dichroism ≈ 0.91), and multiple polarization states, with all features retained over large output angles (over 10°).
