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 ...

Surrogate Scattering Matrix‐Guided Inverse Design of Nanophotonic Neural Networks

Nanophotonics, Volume 15, Issue 18, 25 September 2026.
Surrogate‐guided inverse design separates task learning from electromagnetic realization by transferring a trained passive operator to a fabrication‐aware nanophotonic structure. The electromagnetic cost of each update depends on port count rather than the dataset size.

Geomagnetic Field Influence on Trans‐Ionospheric HF Wave Propagation via Topside Z–to–O Mode Conversion

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Satellite observations during ionospheric modification experiments have reported trans‐ionospheric high‐frequency (HF) wave propagation even when the pump frequency lies below the peak plasma frequency. Such behavior is often attributed to large‐scale density irregularities that locally permit ordinary‐mode (O‐mode) propagation, but this does ...

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 ...
