Global Impacts of Ultra‐Low‐Frequency Waves: 1. Thermospheric Responses and Traveling Atmospheric Disturbances

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Ultra‐low‐frequency (ULF) waves cause local Thermosphere‐Ionosphere (T‐I) perturbations, but their impacts on the global T‐I system including the generation of Traveling Atmospheric Disturbances (TADs) have never been evaluated. The mechanisms responsible for the TAD generation and propagation, whether through dynamic or thermal process, are ...

Steady Collapse of Uranus' Exosphere After 1998 to the Present Decade

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Uranus' thermospheric temperature decreased from ∼800K in 1986 to ∼450K in 2022 as determined from observations of H3+ and H2 infrared emissions. Spitzer 2007 lower atmosphere observations do not emulate this cooling trend. Here we show that the atomic H Lyman ⍺ emission from the disk of Uranus observed by HST from 2011 to 2022 are not ...

Plasmonic‐Quantum and Emitter's Finite‐Size Effects in Plasmon‐Emitter Coupling: A QHT–DFT Hybrid Approach

Nanophotonics, Volume 15, Issue 6, 27 March 2026.
Plasmon‐emitter interactions in a dimer are studied using a hybrid approach: density functional theory captures the molecular transition density of the p‐nitroaniline molecule, whereas quantum hydrodynamic theory models the plasmonic system. Comparison with a point dipole shows significant deviations in emission rates and spectral positions for gaps ...

Short‐Term Variability of Jupiter's Satellite Footprints as Spotted by JWST

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract We present the main Alfvén wing (MAW) spots of Io and Europa as observed by the Near‐Infrared Spectrograph onboard the James Webb Space Telescope. These auroral footprint features have been measured previously, but only in emission. Here, the derived ionospheric H3+ ${\mathrm{H}}_{3}^{+}$ emission, temperature and column density are reported ...

Modeling the EMIC Wave‐Induced Acceleration of Energetic Protons in the Io Footprint Tail

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract The Io footprint tail (FPT) region is crucial for studying the interactions between Io and Jupiter's magnetosphere. In this region, Juno spacecraft observed significant acceleration of energetic protons, concurrently with electromagnetic ion cyclotron (EMIC) waves below the proton gyro‐frequency.

First LiDAR Observation of Quasi‐Periodic Structures in Mid‐Latitude E‐Region Meteoric Ca+ Layers

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract We report the first LiDAR observations of continuous quasi‐periodic (QP) metal density structures in mid‐latitude E‐region meteoric Ca+ layers using an all‐solid‐state LiDAR system in Beijing (40.4°N, 116.0°E). These QP Ca+ structures, with periods of 2–30 min and vertical wavelengths of ∼2–15 km, were primarily observed above 100 km.

Solar Activity Dependence of the Dayside Lunar Surface Potential in the Terrestrial Magnetotail

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract On the dayside of the Moon, the surface potential is primarily determined by (a) photoelectron emission by solar radiation and (b) the ambient plasma environment. Both of these drivers have large variability, but the resulting variability of the lunar surface potential has not been fully characterized yet.

Double Helical Plasmonic Antennas

Advanced Functional Materials, Volume 36, Issue 20, 9 March 2026.
Plasmonic double helical antennas funnel circularly polarized light to the nanoscale, offering strong chiroptical interaction and directional light emission. Extending a single helix design tool, this study combines numerical modeling with experimental validation, revealing large, broadband dissymmetry factors in the visible range.
