High-Accuracy Simulation of Rayleigh Waves Using Fractional Viscoelastic Wave Equation

open access: yesFractal and Fractional, 2023
The propagation of Rayleigh waves is usually accompanied by dispersion, which becomes more complex with inherent attenuation. The accurate simulation of Rayleigh waves in attenuation media is crucial for understanding wave mechanisms, layer thickness ...

Flexible Dielectric Acoustic Resonator Patch for Tissue Regeneration

open access: yesAdvanced Materials, EarlyView.
A flexible dielectric acoustic resonator patch enables MHz‐range ultrasound generation through resonance amplification without using piezoelectric materials. Conformal integration on a curved substrate allows efficient acoustic delivery to tissue‐mimicking environments.

Asymptotic Theory for Rayleigh and Rayleigh-Type Waves [PDF]

open access: yes, 2017
Explicit asymptotic formulations are derived for Rayleigh and Rayleigh-type interfacial and edge waves. The hyperbolic–elliptic duality of surface and interfacial waves is established, along with the parabolic–elliptic duality of the dispersive edge wave on a Kirchhoff plate. The effects of anisotropy, piezoelectricity, thin elastic coatings, and mixed

A Super‐Adhesive Air Filter With Capillarity‐Mediated Spontaneous Particle Absorption via Dynamic Bond Exchange

open access: yesAdvanced Materials, EarlyView.
We address the inherently weak particle adhesion of conventional air filters by coating a dynamically crosslinked adhesive layer that delivers capillarity‐driven strong adhesion and particle absorption mediated by dynamic bond exchange. The resulting enhancement in particle adhesion enables efficient ultrafast (up to 20 m s−1) and omnidirectional ...

A Pseudo-3D Model for Electromagnetic Acoustic Transducers (EMATs)

open access: yesApplied Sciences, 2018
Previous methods for modelling Rayleigh waves produced by a meander-line-coil electromagnetic acoustic transducer (EMAT) consisted mostly of two-dimensional (2D) simulations that focussed on the vertical plane of the material.

Interacting Seismic Waveguides: Multimode Surface Waves and Leaking Modes

open access: yesSeismica, 2023
Recent developments in seismic recording provide dense sampling of the seismic wavefield that allows the extraction of higher surface wave modes as well as the fundamental, and in some circumstances also P-dominated modes.

Weaving Intelligence: Thermally Drawn Multimaterial Fibers Toward AI‐Enabled Smart Textiles

open access: yesAdvanced Materials, EarlyView.
Thermally drawn multimaterial fibers are rapidly advancing as intelligent structural units for next‐generation smart textiles. Integrating multimaterial architectures with neuromorphic and spiking‐neural‐network principles enables fabrics that can sense, compute, and adapt autonomously.

The estimation of the horizontal parameters of gravity waves by the monostatic Rayleigh Lidar

open access: yesScientific Reports
Monostatic Rayleigh Lidar is mainly used for the observation of the middle atmosphere temperature and vertical activity of gravity waves. It was thought that it could not be used for the study of the gravity waves horizontal activity.
