Chainmail-inspired conformable and switchable microwave metamaterial absorber.
Article in Nature communications, 2026. 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
The rigidity of conventional microwave absorbers impedes their reliable integration with complex curved surfaces and deformable components. However, these capabilities remain indispensable for electromagnetic stealth and miniaturized electromagnetic compatibility (EMC) applications that rely on advanced conformal wave-manipulation. To overcome these challenges, we present a chainmail-inspired conformal and switchable microwave metamaterial absorber, conveniently fabricated via 3D printing. The structure exhibits a broadband effective absorption bandwidth (EAB) from 6.2 to 17.6 GHz, while its interlocking topological design enables curvature adaptation without deformation of the absorbing parts. After conformal shaping, the average absorptivity decreases by only 0.049, demonstrating markedly enhanced robustness compared with conventional designs. Furthermore, we integrate the microwave absorber with elastic bands to achieve reversible switching between expanded and contracted states, extending the minimum operating frequency. The optimally configured design achieves a cumulative bandwidth (union of the EABs achieved at 24 cm and 27 cm configurations) from 4.6 to 18 GHz, circumventing the Rozanov limit through dynamic switching. This work provides a practical strategy for realizing switchable ultra-wideband conformal microwave absorbers in diverse electromagnetic applications.
