Simplified radar architecture based on information metasurface.
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 9 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
Modern radar typically employs a chain radio-frequency (RF)-digital architecture, imposing high costs, substantial hardware burdens, and integration challenges. Here, we propose a simplified radar architecture based on space-time-coding (STC) information metasurfaces. With the capabilities to generate multiple frequencies and customize their phases, the STC metasurfaces play crucial roles in both transmission and reception: they enable chirp signal generation and radiation at the transmitter while facilitating echo reception and dechirp processing at the receiver. Remarkably, dechirp processing is performed at the RF level, removing the need for high-speed digitization and potentially enabling more efficient signal processing than conventional digital methods. As a proof of concept, experiments demonstrate that the proposed metasurface radar achieves target detection and range/speed measurement performance comparable to that of conventional systems. This study presents an innovative radar system paradigm that integrates RF front ends and signal processors onto an information metasurface platform, achieving essential sensing functions with reduced system complexity and cost.
