Fast Simulation of Wide‐Angle Coherent Diffractive Imaging
Laser &Photonics Reviews, EarlyView.The propagation multi‐slice Fourier transform method is introduced as an accurate and efficient approach for describing light scattering for arbitrarily shaped objects. Its exceptional suitability for simulating coherent diffractive imaging of nanoparticles in the XUV and soft X‐ray range is demonstrated.

Mode‐Locked Pulse Generation in Plasmonic Lattices
Laser &Photonics Reviews, EarlyView.The plasmonic superlattices overlaid with optically pumped organic molecules produce multimode lasing due to mid‐range radiative coupling (MR‐RC, lambda) and long‐range radiative coupling (LR‐RC, 10 lambda). Right: The mode locking emerges spontaneously due to the shared excited state molecular populations which may emit photons to various different ...

Reconfigurable Circularly Polarized Terahertz Emission from vdW Ferroelectric NbOI2
Laser &Photonics Reviews, EarlyView.A controllable chiral terahertz pulse can be generated using a simple dual‐flake vdW ferroelectric NbOI2 emitter in which the polar axes of the two NbOI2 flakes are orthogonal. Both the chirality and the ellipticity can be manipulated by varying the separation distance and the orientations of their polar axes.

Progress in Photovoltaics: Research and Applications, EarlyView.This study presents a novel, nondestructive in situ method to quantify water ingress using near‐infrared absorption (NIRA) spectroscopy, calibrated with absolute water content via Karl–Fischer titration (KFT). The presented approach offers a powerful quality assurance and inspection tool for module manufacturers and solar developers, supporting ...

Sensitivity of flower trade‐wind cloud organisation to mesoscale atmospheric heterogeneities
Quarterly Journal of the Royal Meteorological Society, EarlyView.Trade‐wind cloud organisation is insensitive to dynamical and thermal heterogeneities but very sensitive to humidity mesoscale heterogeneities, especially in the cloud layer, where they form moist patches, and not in the sub‐cloud layer. Clouds and rain develop in moist patches, then cold pools develop progressively, initiating mesoscale circulations ...

Polarization‐Dependent Elliptical and Rectangular Mie Voids
Small, EarlyView.Polarization‐dependent Mie void resonances are realized by introducing anisotropic low‐index inclusions embedded in high‐index materials. Elliptical and rectangular void geometries enable controlled tuning of resonance behavior and optical mode formation.
