Global Observational Comparison of Large‐Scale Traveling Atmospheric and Ionospheric Disturbances During the May 2024 Geomagnetic Storm

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract During the geomagnetic storm on 10 May 2024, neutral density measurements from 14 Tianmu, Swarm, and GRACE‐FO satellites at ∼510 km altitude, combined with total electron content (TEC) observations, enabled the first global observational comparison of large‐scale traveling atmospheric and ionospheric disturbances (LSTADs/TIDs) via snapshots ...

Dynamic Holographic Display With Multiplexed Dielectric Metasurfaces

Nanophotonics, Volume 15, Issue 12, 25 June 2026.
Based on multiplexed metasurfaces, we show hybrid multiplexing of polarization, wavelength, and orbital angular momentum can be applied for dynamic tuning. Our strategy presents a highly compact and efficient solution for high‐capacity, multi‐dimensional holography, with promising applications in advanced displays, data storage, optical encryption, and

Engineering Angular Dispersion via Hybrid Local–Nonlocal Metasurfaces

Nanophotonics, Volume 15, Issue 12, 25 June 2026.
A single‐layer hybrid local–nonlocal silicon metasurface is experimentally demonstrated as a polarization‐insensitive angular filter in transmission. By combining local nanopillar response, lattice‐mediated interactions near the Rayleigh anomaly, and diffraction‐assisted substrate coupling, the platform maintains high transmission within a ±15° $\pm ...

Magnetically Reconfigurable Mode Strong Coupling Toward Tunable Nanophotonic Sensing Devices

Nanophotonics, Volume 15, Issue 12, 25 June 2026.
A magnetically reconfigurable metasurface realizes tunable strong coupling between structural and magneto‐structurally induced q‐BIC resonances without changing device geometry. The resulting hybrid branches enable high‐sensitivity refractive‐index sensing with noncontact active control, large figure of merit, and multiple resonance observables ...

Revealing Coastal Storm‐Wave Transformations From SWOT HR Observation: The English Channel Case Study

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Swell propagation and transformation across variable bathymetry and coastal obstacles fundamentally control nearshore wave energy redistribution, sediment transport, and shoreline evolution. Conventional satellite altimetry cannot adequately resolve these dynamics, particularly refraction and diffraction as swell transition into shallow waters.

Multi‐Step Gravity Wave Propagation From a Tropospheric Vortex to the Ionosphere Near the Tibetan Plateau

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract The atmosphere and ionosphere form a vertically coupled system in which disturbances in the lower atmosphere can modulate ionospheric variability. Using reanalysis data, ground‐based GNSS observations, and COSMIC‐2 profiles, we investigate gravity waves (GWs) generation and upward coupling during a southwest vortex (SWV) event over the Tibetan

Wavefront Aberrations and Peripheral Vision

, 2007
Failing eyesight causes a dramatic change in life. The aim of this project is to help people with large central visual field loss to better utilize their remaining vision. Central visual field loss means that the person has to rely on peripheral vision since the direct vision is lost, often due to a dysfunctional macula.
