First Detection of the Two‐Dimensional Vertical Propagation of Traveling Ionospheric Disturbances Associated With Atmospheric Gravity Waves in the Martian Ionosphere

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract We report the detection of a traveling ionospheric disturbance (TID) captured by the Mars Advanced Radar for Subsurface and Ionosphere Sounding (MARSIS) Active Ionospheric Sounding (AIS) instrument aboard the Mars Express spacecraft at 150–250 km altitude.

Conjugate Ionospheric Electron Density Irregularities Induced by Very Low Frequency Transmissions at North West Cape, Australia

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract This study investigates the characteristics of ionospheric electron density irregularities induced by very low frequency (VLF) wave transmissions from North West Cape (NWC), Australia, using Swarm‐A satellite data from January 2014 to September 2024.

Electromagnetic Quasinormal Modes: A Foundational Framework for Describing Fano Resonances of Extinction Spectra

Nanophotonics, Volume 15, Issue 9, 13 May 2026.
An ab initio electromagnetic framework links quasinormal modes to Fano resonances in extinction spectra. Analytical expressions for the Fano asymmetry and intensity parameters are derived from overlap integrals, enabling rapid spectral reconstruction and physical interpretation.

Euler‐Top Gaussian Modes: Structured Beams From Quadratic Angular Momentum Dynamics

Nanophotonics, Volume 15, Issue 9, 13 May 2026.
A new family of structured Gaussian light beams are introduced: Euler‐top Gaussian modes. Their ray‐orbital paths on the Gaussian Poincaré sphere correspond to the polhodes of the Euler top in classical angular momentum theory. This geometric and algebraic construction reveals a nonseparable mode family extending the familiar Hermite‐, Laguerre‐ and ...

Electrically Reconfigurable Quasi‐BIC Metadevices Enabled by Integrated Barium Titanate

Nanophotonics, Volume 15, Issue 9, 13 May 2026.
An electrically reconfigurable quasi‐BIC metasurface is demonstrated by monolithic integration of barium titanate. Leveraging the Pockels effect, linear tuning of 1.79 nm/V is achieved, enabling a 250 μm2 miniaturized spectrometer with 0.2 nm resolution, 99% fidelity, and high throughput.
