1 · What the graph read from it

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.

2 · The registry

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

We theoretically analyze the enhancement and regulation of Goos-Hänchen (GH) shift in hyperbolic metamaterials in the near-infrared band. For a given incident wavelength, photonic crystals composed of graphene and dielectric present hyperbolic dispersion characteristics by modulating the Fermi energy of graphene. The phase of the reflection coefficient changes dramatically near the phase transition from hyperbolic dispersion to elliptic dispersion, and subsequently giant GH shift is achieved at the resonant angle. The largest GH shift is as high as 300λ. Great GH shift can be effectively realized by regulating the layers of graphene and the thickness of the dielectric as well. It is hoped that this research may provide theoretical guidance for the design of high-sensitivity sensors based on the GH shift effect in hyperbolic metamaterials.
