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 ...

Inverse‐Designed Nanophotonic Structures for On‐Chip Excitation and Broadband Emission Extraction in Diamond Quantum Spin Sensing

Nanophotonics, Volume 15, Issue 17, 11 September 2026.
Inverse‐designed nanophotonic structures on a foundry‐compatible silicon nitride chip enable efficient in‐plane green excitation and broadband red emission extraction from diamond nitrogen‐vacancy centers. A compact emitter triples the guided optical power, while a directional coupler routes ∼80% of the fluorescence to detection, advancing miniaturized

Vectorial Diffractive Neural Metasurfaces for Multiplexed Synthesis of Optical Skyrmions

Nanophotonics, Volume 15, Issue 17, 11 September 2026.
A three‐layer Jones‐matrix‐based vectorial diffractive neural network enables compact, passive, and multiplexed synthesis of optical skyrmions and bimerons. By mapping distinct Gaussian‐beam input channels to coaxial orbital‐angular‐momentum and polarization states, the device generates up to 16 topological vector textures with high mode purity, robust
