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

The discovery of photonic higher-order topological insulators (HOTIs) has expanded our understanding of band topology, offering robust lower-dimensional boundary states for photonic devices. However, realizing three-dimensional (3D) photonic HOTIs remains challenging due to the vectorial and leaky nature of electromagnetic waves. Here, we present the experimental realization of a 3D Wannier-type photonic HOTI using a tight-binding-like metal-cage photonic crystal, whose band structures align with a 3D tight-binding model via confined Mie resonances. Microwave near-field measurements reveal coexisting topological surface, hinge, and corner states in a single 3D photonic HOTI, consistent with theoretical predictions. Remarkably, these states are robust and self-guided even within the light cone continuum, functioning without ancillary cladding. This work paves the way for multi-dimensional manipulation of electromagnetic waves on 3D cladding-free photonic bandgap materials, enabling practical applications in 3D topological integrated photonic devices.
