Frozen Differential Scattering in Reconfigurable Complex Media
A localized perturbation universally results in a rank‐one update of the scattering matrix of any complex medium. The resulting differential output wavefront is “frozen”: its spatial pattern is fixed (agnostic to the input wavefront). Experiments with a programmable‐metasurface‐parametrized wireless link validate frozen differential scattering and ...

Explosion process of propylene oxide (PO)/Al/AlH3/air was investigated. The PO/Al/AlH3/air multiphase clouds under strong ignition detonation have reached a quasi‐detonation state. ABSTRACT Fuel‐air explosives (FAE) are an important source of explosion energy. The density advantage of aluminum hydride (AlH3) dust is obvious compared with that of liquid

Abstract Nonlinear simulations of the feedback instability in the Alfvénic magnetosphere‐ionosphere (M‐I) coupling system have been carried out by means of the reduced magnetohydrodynamic (MHD) equations with spatially non‐uniform kinematic viscosity and resistivity, coupled with two‐fluid equations, in order to investigate auroral fine‐structure ...

Abstract Earthflows are landslides in fine‐grained materials that alternate long dormant phases of very slow movement with short paroxysmal stages of rapid motion. These rapid phases are highly destructive, often causing severe damage to buildings and infrastructure.

Abstract Ejections of magnetized plasma from the Sun, known as coronal mass ejections, can drive major geomagnetic activity if Earth‐directed, and are therefore monitored by space weather forecasters. The current focus being the forecast of the arrival time of a coronal mass ejection at Earth and the level of geomagnetic impact.

Unsupervised Deep Representation Learning for Infrasound Phase Identification
Abstract Infrasound phase identification is challenging because atmospheric variability strongly influences signal propagation on short timescales that are not resolved by standard atmospheric models. While traditional approaches rely on propagation modeling and array‐derived parameters, recent work suggests that waveform structure itself encodes ...

Abstract The Kelvin‐Helmholtz instability (KHI) mediates the viscous‐like solar‐terrestrial interaction by generating magnetopause surface waves that quickly become non‐linear. Basic theory predicts the locally most‐unstable linear wave dominates.

Achromatic Petal‐Shaped Beam Generation and Information Encoding Based on Perfect Vortex Beam
Based on petal‐shaped beams with controllable topological charge, size, and rotation angle, this work employs a spatially multiplexed all‐dielectric TiO2 transmissive array to numerically achieve achromatic petal‐shaped beams at three wavelengths: 480 nm, 530 nm, and 630 nm. Leveraging their unique intensity distribution and rotational characteristics,
