High‐Order Multipolar Excitations Governing Circular Dichroism in an All‐Dielectric Chiral Metasurface

Nanophotonics, Volume 15, Issue 11, 13 June 2026.
An all‐dielectric asymmetric gammadion metasurface exhibits visible circular dichroism governed by helicity‐selective multipolar excitations. Quadrupole‐dominated and weaker mixed‐mode resonances are identified, and their distinct near‐field optical chirality and angular responses are revealed, establishing a direct link between structural asymmetry ...

Reconfigurable Spoof Plasmonic Skyrmion Electronics for Deformation‐Invariant Multimode Sensing

Advanced Science, Volume 13, Issue 34, 19 June 2026.
A flexible multimode sensor based on capacitively loaded spoof plasmonic skyrmions enables deformation‐invariant dielectric sensing with ultra‐compact size and high Q‐factor. Near‐equidistant resonances remain stable under shape change and bending, while capacitor loading improves bending robustness and multimode sensitivity, highlighting strong ...

Frozen Differential Scattering in Reconfigurable Complex Media

Laser &Photonics Reviews, Volume 20, Issue 11, 5 June 2026.
A localized perturbation universally results in a rank‐one update of the scattering matrix of any complex medium. The resulting differential output wavefront is “frozen”: its spatial pattern is fixed (agnostic to the input wavefront). Experiments with a programmable‐metasurface‐parametrized wireless link validate frozen differential scattering and ...

Wafer‐Scale Deterministic Fabrication of Axis‐Ratio–Engineered Silicon Nanoparticles for On‐Resonance Electric–Magnetic Dipole Interference

Small, Volume 22, Issue 32, 8 June 2026.
Wafer‐scale top‐down fabrication yields silicon nanoparticles with exceptional uniformity (CV 1.7%–2.4%), enabling deterministic axis‐ratio tuning. At AR ≈$\approx$ 2.1, electric–magnetic dipoles overlap on‐resonance, producing near‐Kerker forward scattering (F/B ≈$\approx$ 12.5).

Quasi‐BIC and Reflective Mode Coupling Drives SHG Beyond the Q Factor Limit

Small, Volume 22, Issue 32, 8 June 2026.
An analytical expression is developed to relate second‐harmonic generation to both the resonance Q factor and absorptance. Simulations and experiments on a dual‐resonance 3R‐MoS2 metasurface validate the formula, showing that absorptance engineering provides an effective route to enhance SHG beyond conventional Q‐only design.

Achromatic Petal‐Shaped Beam Generation and Information Encoding Based on Perfect Vortex Beam

Nanophotonics, Volume 15, Issue 10, 27 May 2026.
Based on petal‐shaped beams with controllable topological charge, size, and rotation angle, this work employs a spatially multiplexed all‐dielectric TiO2 transmissive array to numerically achieve achromatic petal‐shaped beams at three wavelengths: 480 nm, 530 nm, and 630 nm. Leveraging their unique intensity distribution and rotational characteristics,

Low‐Frequency, Ultra‐Thin and Ultra‐Wideband Meta‐Absorber via Resonance Enhancement Harnessing Magnetic Material

Nanophotonics, Volume 15, Issue 10, 27 May 2026.
This work proposes a novel strategy to integrate ultra‐wideband absorption and ultra‐thin thickness for low‐frequency P–S bands. A composite metamaterial absorber is verified experimentally by synergistically combining a customized three‐layer resonant structure with a top‐loaded magnetic material layer.
