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 ...

Misaligning Cascaded Liquid Crystal Elements for Continuously Tunable Axial Spin‐Dependent Splitting
Nanophotonics, Volume 15, Issue 17, 11 September 2026.Continuously tunable axial spin splitting is achieved by controlling the lateral misalignment of cascaded Pancharatnam‐Berry phase liquid crystal elements. The displacement generates a spin‐dependent quadratic phase, enabling linear, sign‐reversible focal adjustment and dynamic focus interchange for orthogonal circular polarizations.

Dynamic Control of Phase Matching in Nonlinear Metasurfaces Using Pancharatnam–Berry Phase
Nanophotonics, Volume 15, Issue 17, 11 September 2026.Can mechanical rotation of a metasurface control the phase of a nonlinear optical signal? In a dual‐metasurface multipass cell, a circularly polarized pump interacts repeatedly with two plasmonic metasurfaces between two mirrors. By exploiting the geometric phase, rotating one metasurface shifts the phase‐matching condition of the second‐harmonic ...

Direct Observation of Propagating Spin Waves in a Spin Hall Nano‐Oscillator
Advanced Materials, Volume 38, Issue 52, 16 September 2026.By combining frequency injection locking with time‐resolved scanning transmission x‐ray microscopy (TR‐STXM), the authors image the real‐time magnetization dynamics of a spin Hall nano‐oscillator (SHNO) for the first time. Their results reveal richer dynamics than previously reported and challenge existing assumptions regarding the radiation hardness ...

Enhancement of Circular Dichroism in Chiral Dielectric Metasurfaces by Ion Beam Irradiation
Advanced Optical Materials, Volume 14, Issue 35, 18 September 2026.Ion beam irradiation enables post fabrication tuning of dissipative losses in chiral dielectric metasurfaces composed of C4 symmetric silicon nanostructures. By tailoring the absorption toward critical coupling condition, circular dichroism is enhanced from 0.70 to 0.85, demonstrating a versatile route for maximizing optical chirality and polarization ...
