Metalens‐Enabled Twisted Chromatic Dispersion
Advanced Physics Research, Volume 5, Issue 5, May 2026.We successfully demonstrate visible broadband twisted dispersion metalenses. As a proof of concept, we realized two distinct devices: the conical helical and the spring‐like dispersion‐controlled metalenses. These results rigorously validate the universality of our approach in customizing arbitrary continuous 3D dispersion trajectories, thereby ...

Neural Network–Assisted Metasurface Retroreflector With Wide‐Angle Adaptivity
Electron, Volume 4, Issue 2, May 2026.This work proposes a wide‐angle, multi‐polarization, self‐sensing, and self‐adaptive intelligent metasurface retroreflector, with a planar profile and ultrathin thickness. By integrating a pre‐trained artificial neural network (ANN), the metasurface retroreflector can recognize the incident angle and promptly adapt to changes in the incoming wave.

Dynamic Multifunctional Metasurfaces Based on Passive Cascade Structure
Electron, Volume 4, Issue 2, May 2026.A dynamic multifunctional metasurface is proposed in this paper. Unlike mainstream multifunctional metasurface based on programmable metasurfaces, it consists of two passive metasurfaces, presenting a significant cost advantage. By controlling the displacement, different functions such as beam steering, focusing, and OAM wave generation can be realized

InfoMat, Volume 8, Issue 5, May 2026.Bidirectional photo response in a two‐dimensional heterojunction photodetector controlled by light wavelength and polarization. Abstract Polarization is one of the most fundamental properties of light. Traditional polarization‐sensitive photodetectors, however, are limited in their ability to fully extract this information, as they translate the two ...

Intelligent materials for on‐demand electromagnetic absorption
InfoMat, Volume 8, Issue 5, May 2026.This review introduces an innovative “stimulus‐state‐property” paradigm, facilitating a fundamental transition from static to dynamically intelligent electromagnetic wave absorption (EMWA). The key advancement lies in the synergistic integration of external fields with structurally engineered metamaterials and tunable components.
