Multichannel wavefront manipulation via wavelength-polarization multiplexed terahertz metadevice.
Article in iScience, 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
As the two-dimensional counterpart of metamaterials, metasurfaces have demonstrated exceptional potential in optics due to their remarkable ability to flexibly manipulate electromagnetic waves, offering a platform for multidimensional wavefront manipulation. However, existing multiplexing techniques predominantly focus on a single physical dimension, and multi-parameter joint multiplexing still faces challenges such as limited design degrees of freedom and channel crosstalk. This paper proposes a wavelength-polarization multiplexed terahertz metadevice based on anisotropic meta-atoms, which enables independent wavefront manipulation of three-band responses under orthogonal linear polarizations within a single-layer structure, thereby creating six fully decoupled transmission channels. We designed and numerically validated a dual-polarization triple-frequency decoupled metalens, a dual-polarization achromatic vortex beam generator, and a six-channel holographic display device. This research provides a compact and efficient solution for multidimensional optical field manipulation, with promising applications in terahertz communications, high-capacity information encryption, and holographic displays.
