Dipole‐Quadrupole Model and Multipole Analysis of Resonant Membrane Metasurfaces

Laser &Photonics Reviews, EarlyView.
Membrane metasurfaces, arrays of holes in a dielectric membrane, are appealing because they require no substrate and allow access to resonant near‐fields. However, developing a comprehensive theoretical description for them remains challenging. We introduce a semi‐analytical dipole‐quadrupole approach to analyze their resonant spectra at arbitrary ...

Frontiers of Bright CEP‐Stable Broadband Infrared Sources

Laser &Photonics Reviews, EarlyView.
Bright CEP‐stable broadband infrared sources push the limits of ultrafast science by delivering exceptional brightness alongside few‐cycle durations and multi‐octave spectral coverage. This review highlights emerging architectures and nonlinear conversion strategies that scale power while preserving phase stability.

Giant Phonon‐Enhanced Terahertz Electro‐Optic Response in Ferroelectric van der Waals NbOX2 (X = Br, I)

Laser &Photonics Reviews, EarlyView.
Van der Waals ferroelectric NbOX2 thin films exhibit phonon‐resonance enhanced electro‐optic responses, 332 pm/V at 3.1 THz (NbOI2) and 192 pm/V at 3.7 THz (NbOBr2), the highest among vdW materials, and show 4% non‐resonant SHG modulation together with resonant phonon‐enhancement under a 150 kV/cm THz pump.

Impact of small‐scale gravity waves on tracer transport

Quarterly Journal of the Royal Meteorological Society, EarlyView.
We extend a gravity wave (GW) parametrization to calculate the tracer transport due to the GW–Stokes drift and next‐order effects, where the approach is validated by comparing coarse‐resolution simulations with parametrized GWs to high‐resolution, wave‐resolving reference simulations.

Medicane characteristics from high‐resolution satellite radar observations

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This study uses high‐resolution observations from satellite synthetic aperture radar (SAR) to reveal that medicanes, cyclones with tropical features in the Mediterranean basin, have dynamical characteristics with attributes comparable with those of tropical cyclones of similar intensities, but smaller outer sizes and Rossby numbers.
