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 ...

Lie group analysis, solitons, self-adjointness and conservation laws of the nonlinear elastic structural element equation

Journal of Taibah University for Science
This study is based on the Lie group method for the nonlinear elastic structural element equation (ESE Equation). We obtain a three-dimensional Lie algebra. By utilizing this Lie algebra a four-dimensional optimal system is constructed. The governing ESE

Dimensional Synthesis for Emulating Nonlinear Disclination Dynamics

Nanophotonics, Volume 15, Issue 17, 11 September 2026.
(a) Intensity distributions of the 2D disclination lattice under corner‐site excitation in the linear (a1), weakly nonlinear (a2), and strongly nonlinear (a3) regimes. (b) Corresponding one‐dimensional synthesized lattices (1DSLs) obtained through Lanczos mapping under the same nonlinear regimes.

Microring Resonator Dispersion Metrology With Neural Networks

Nanophotonics, Volume 15, Issue 17, 11 September 2026.
We present a machine learning framework for inverse and forward characterization of microring resonators, inferring geometry and material dispersion from sparse spectral data. The approach achieves nanometer‐scale accuracy and > 99% material identification, while reconstructing full dispersion spectra.

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 ...

Seven‐Fold Compression of Mid‐Infrared Pulses Using a Series of Titanium Dioxide Plates

Advanced Optical Materials, Volume 14, Issue 35, 18 September 2026.
Here, a sequence of three titanium dioxide plates is used to compress a mid‐infrared pulse from 103.9 femtoseconds to 14.1 femtoseconds (about two optical cycles) without the use of external dispersion compensation. The approach maintains high efficiency and produces pulses with a stable carrier‐envelope phase, providing a compact platform for ...

Toward 100‐Watt‐Level Mid‐Infrared Supercontinuum Light Generation

Advanced Photonics Research, Volume 7, Issue 9, September 2026.
Output power of mid‐infrared supercontinuum (SC) light sources severely prevents their application in long‐distance remote sensing, hyperspectral imaging, directional infrared countermeasures, and so forth. This work demonstrates a 100‐watt‐level all‐fiber mid‐infrared SC light source based on homemade low‐loss (~0.022 dB/m) fluorotellurite glass ...
