Tunable Sound Absorption via Evanescent‐Wave Coupling in Asymmetric Bilayer Metasurfaces

Advanced Science, Volume 13, Issue 20, 9 April 2026.
Tunable sound absorption is realized through a bilayer metasurface system governed by evanescent‐wave coupling. This work demonstrates that such evanescent‐wave coupling provides a controllable scattering channel that destructively interferes with the specular reflection.

Diamond Metasurface‐Based Optical Tweezers With Enhanced Robustness

Advanced Science, Volume 13, Issue 19, 2 April 2026.
Conventional metasurface optical tweezers are hindered by thermal instability from laser heating. This work overcomes this by using diamond metasurfaces, exploiting their low thermo‐optic coefficient and minimal thermal expansion. The platform demonstrates stable particle trapping, translocation, and rotation, enabling robust miniaturized systems for ...

Real‐Time, Label‐Free Classification of Cell Death Pathways via Holotomography‐Based Deep Learning Framework

Advanced Intelligent Systems, Volume 8, Issue 4, April 2026.
A 3D holotomography system coupled with a deep learning model distinguishes how cells die—apoptosis, necroptosis or necrosis—without any fluorescent labels. Training on refractive index maps of HeLa cells yields 97% accuracy and flags necroptosis hours before chemical dyes.

Software‐Defined Terahertz Beam Manipulation via Active Light‐Controlled Frequency Coding Information Metasurface

Advanced Physics Research, Volume 5, Issue 4, April 2026.
This paper proposes an integrated active light‐controlled frequency coding metasurface and a software‐defined array control system. Utilizing spatially encoded structured light and a “Decision‐Optimization‐Execution” intelligent closed‐loop architecture, the system overcomes traditional electrical control interference, achieves real‐time dynamic ...

One Metasurface for Four‐Channel Terahertz Wavefront Manipulation Based on Vanadium Dioxide

Advanced Physics Research, Volume 5, Issue 4, April 2026.
This article presents a thermally reconfigurable metasurface utilizing vanadium dioxide (VO2) to dynamically switch between four independent wavefront‐manipulation channels. By synergizing geometric and propagation phases, the platform enables spin‐decoding for circularly polarized waves and polarization multiplexing for linearly polarized waves ...
