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

Nanophotonics, 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.

Architectural Tailoring and Reinforcement Strategies for Improved Bearing Strength in Thick Carbon Fiber/Epoxy Laminates

Polymer Composites, Volume 47, Issue 20, Page 18791-18811, 20 October 2026.
Schematic overview of the investigated laminate architectures and reinforcement strategies used to evaluate their effects on the bearing performance and failure behaviour of thick carbon fibre/epoxy laminates. ABSTRACT This study provides a unified experimental comparison of 11 joint configurations in thick (7–12 mm) vacuum‐infused CFRP laminates ...

Shallow Poroelastic Hydrothermal Deformation at Changbaishan Volcano Before the 2020 Unrest Revealed by Sentinel‐1 InSAR Time Series

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Ground deformation of dormant volcanoes provides critical insights into subsurface processes and potential hazards. Here we present Sentinel‐1 Interferometric Synthetic Aperture Radar (InSAR) time series (2015–2020) for Changbaishan volcano, the largest intraplate volcanic system in East Asia. We detect persistent subsidence of up to 3.5 mm/yr

Microphysics and Kinematics of a High Flash Rate Storm With a Bottom‐Heavy Charge Structure

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 19, 16 October 2026.
Abstract An atypical thunderstorm with unusual lightning and charge structure characteristics propagated through Cordoba province, Argentina, during the austral warm season in late 2018. This storm exhibited echo tops near 10.5 km, with high lightning activity concentrated at low altitudes.

Scalable Multi‐Target Illusion via a Segmented Spatiotemporal Metasurface

Nanophotonics, Volume 15, Issue 19, 13 October 2026.
An electromagnetic kaleidoscope is realized with a segmented spatiotemporal metasurface that transforms one physical aperture into multiple independently controlled false targets. Parallel‐sequence spectral translation codes apparent range and velocity, while segment allocation regulates echo amplitude. Experiments at 5 GHz generate two to five targets
