Wavelength‐Selective Nonlinear Wavefront Control in Resonant Thin‐Film Lithium Niobate Metasurfaces
Advanced Photonics Research, Volume 7, Issue 10, October 2026.A LN metasurface converts a Gaussian pump beam into a first‐order Hermite–Gaussian second‐harmonic beam, exploiting spectrally distinct Mie‐type resonances across two nanostructured regions. The resonance‐engineered phase difference enables wavelength‐selective wavefront shaping, active only within a specific spectral window, while leaving the ...

Journal of Biophotonics, Volume 19, Issue 10, October 2026.Compared with single‐photon methods, TPM enables deep‐tissue imaging using near‐infrared light, with excitation confined to the focal plane, thereby reducing photodamage. SHG microscopy images noncentrosymmetric biological structures such as collagen and myosin without fluorescent labels, offering direct structural contrast.

Journal of Arrhythmia, Volume 42, Issue 5, October 2026.Analyzing 48 153 CARTOFINDER mapping points revealed that both FoA and RoA sites demonstrated elevated DF deviation (DFD) and RI compared to non‐sites. While both metrics increased progressively with FoA repetitions, high‐repetition RoA sites paradoxically displayed lower values.

Understanding higher‐order aberrations in keratoconus
Optometry and Vision Science, Volume 103, Issue 10, October 2026.ABSTRACT Keratoconus is characterized by progressive thinning and increasing irregularity of the cornea, leading to substantial degradation in optical quality through the induction of both lower‐ and higher‐order aberrations (HOAs). In addition to inducing myopic and astigmatic refractive error, asymmetric corneal steepening generates complex optical ...

Ultrasonic Vibration Assisted Laser Processing: A Hybrid Paradigm for Extreme Surface Enhancement
Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Traditional laser processing techniques offer many advantages, but they often encounter limitations such as heat‐affected zones, recast layers, residual tensile stresses, and poor surface finish. The integration of ultrasonic vibration (UV) presents a promising hybrid approach to overcome these challenges by introducing beneficial effects like

Design of Large‐Aperture Hybrid Refractive Metalens System
Nanophotonics, Volume 15, Issue 18, 25 September 2026.An all‐germanium hybrid refractive–metalens system was constructed by integrating a planar Ge metalens with a single aspheric Ge lens, enabling compact wavefront correction in the LWIR band. The all‐Ge hybrid architecture simplifies conventional multi‐element infrared optics into a lightweight integrated imaging system while maintaining effective ...

Fault‐Controlled Plumbing System Beneath Lipari Volcanic Island Revealed by Seismic Matrix Imaging
Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.Abstract Lipari Island hosts an active magmatic–hydrothermal system, but its deep plumbing architecture remains poorly resolved due to strong seismic scattering. We apply passive seismic matrix imaging to public vertical‐component cross‐correlation functions from the dense 2018 Lipari nodal array, recovering relative‐reflectivity structures to ∼10 km ...

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.Abstract This study demonstrates the intriguing and complex interplay among auroral precipitation, enhanced TEC, density irregularities, and amplitude scintillations observed during the November 2025 superstorm. For the first time, we present observations of strong amplitude scintillation across continental United States (CONUS)—nearly from coast to ...

Dynamic Generation of Spatially Variable Vector Beams Using Cascaded Moiré Metasurfaces
Nanophotonics, Volume 15, Issue 17, 11 September 2026.A three‐layer cascaded moiré metasurface dynamically generates vector beams with tunable polarization order and controllable lateral focal positions. Relative rotation of the first two layers adjusts the conjugate OAM components that form the vector beam, whereas the third layer steers its focus across the transverse plane, preserving the dominant OAM ...
