Weak Measurement for Characterizing Effective Jones Matrices of Phase Gradient Metasurfaces

open access: yesLaser &Photonics Reviews, EarlyView.
Spin dependent deflection from a PB phase gradient metasurface is converted by two dimensional weak measurement into a centroid map, where the amplitude ratio, phase difference, and phase gradient produce distinct spatial features. These effective parameters are then retrieved directly from the centroid response.

Wear‐Activated Surface Engineering of Thermoplastic Polyurethane/Graphene Nanoplatelet Nanocomposites for Ice Friction Control

open access: yesPolymer Composites, EarlyView.
Wear‐activated surface engineering of TPU/GNP nanocomposites through improved filler dispersion and interfacial anchoring of functionalized graphene nanoplatelets, leading to finer post‐abrasion textures and enhanced ice traction. ABSTRACT Graphene‐reinforced thermoplastic polyurethane (TPU) composites offer a promising route for developing ...

All‐Optical Dual‐Angle Diffractive Neural Networks for 2D Direction‐of‐Arrival Estimation

open access: yesNanophotonics, Volume 15, Issue 20, 27 October 2026.
A diffractive neural network with an integrated spatial encoder resolves the direction of an incoming terahertz signal entirely through optical propagation. After the signal passes through the cross‐shaped input and two 3D‐printed diffractive layers, two detector arrays read its two incident angles simultaneously.

Wide‐Angle Domain Compatible Flexible Multispectral Stealth Metasurface for Visible Light, Laser, and Microwave

open access: yesNanophotonics, Volume 15, Issue 20, 27 October 2026.
A flexible, wide‐angle‐compatible multispectral stealth metasurface is proposed. It achieves visible camouflage and stable cooperative stealth of 10.6 μm laser and X‐band microwave across the 0°–60° incident range via layered wavelength decoupling. ABSTRACT As electromagnetic detection systems evolve toward multispectral integration and 0°–60° wide ...

Reconfigurable Light Field Generation With Hologram‐Enhanced Multicore Fibers

open access: yesNanophotonics, Volume 15, Issue 20, 27 October 2026.
A novel metafiber platform enables reconfigurable generation of structured light patterns directly at the end of a multicore optical fiber. A 3D‐printed hologram maps individual fiber cores onto predefined image elements, allowing programmable pattern synthesis through selective core excitation.
