Full‐Space Terahertz Airy Beam Shaping via Composite Bilayer Metasurface With Switchable Amplitude–Phase Encoding Channels

Nanophotonics, Volume 15, Issue 21, 12 November 2026.
A composite bilayer metasurface integrates linear‐polarization amplitude–phase modulation with circular‐polarization Pancharatnam–Berry phase modulation, enabling multidimensional terahertz Airy beam manipulation within a single compact aperture. The highly integrated platform supports diverse Airy beam generation and offers new opportunities for ...

Cracking the Code: Which Ocular Symptoms Predict Dry Eye Signs? Insights From a Large International Sicca Registry

Arthritis Care &Research, Volume 78, Issue 11, Page 1679-1690, November 2026.
Objective The study aimed to identify symptom‐based predictors of dry eye disease (DED) signs in the Sjögren's International Collaborative Clinical Alliance (SICCA) cohort. Methods We performed a retrospective analysis examining 16 ocular symptoms (most graded 0–4) and artificial tear (AT) use (graded 0–3) as predictors of DED signs (abnormal ocular ...

Drop‐on‐Demand Printed Negative Dielectric Anisotropy Liquid Crystal Droplets for Adaptive Complex Beam Manipulation and Assessment

Advanced Functional Materials, Volume 36, Issue 89, 5 November 2026.
Printed negative‐dielectric‐anisotropy liquid‐crystal droplets enable multidimensional full‐vectorial optical‐field sensing across polarization, phase, and wavelength, while also generating tunable skyrmionic‐like complex optical fields. ABSTRACT Adaptive manipulation of vectorial optical fields is important for optical metrology, imaging, and ...

Basis‐Independent Geometric Phase Modulation in Circularly Birefringent Plasmonic Structures

Advanced Optical Materials, Volume 14, Issue 41, 6 November 2026.
Here we introduce a plasmonic metasurface composed of spatially rotated chiral spiral unit cells designed to produce space‐variant circular retardance. This generates a geometric phase ramp equivalent to a blazed grating, leading to polarization dependent diffraction orders in momentum space.

Neuromorphic Optical Tracking and Imaging of Randomly Moving Targets Through Dynamic Dense Scattering Media

Advanced Science, Volume 13, Issue 63, 12 November 2026.
Vision begins not with images but with change: the retina fires only when something moves, handing the brain a stream of spikes. A neuromorphic imaging system adopts the same strategy—an event sensor that sees like the retina, a spiking network that thinks like the brain—to track and reconstruct fully randomly moving targets through tissue (phantom ...
