Superscattering of water waves. [PDF]
Natl Sci Rev, 2023 ABSTRACT Inspired by the concept of superscattering in optics, we for the first time theoretically predict and experimentally demonstrate the superscattering phenomenon in water waves. The subwavelength superscatterer is constructed by multi-layered concentric cylinders with an inhomogeneous depth profile.

Steady Water Waves with Multiple Critical Layers
SIAM Journal on Mathematical Analysis, 2011 We construct small-amplitude periodic water waves with multiple critical layers. In addition to waves with arbitrarily many critical layers and a single crest in each period, two-dimensional sets of waves with several crests and troughs in each period ...

Observations of Cherenkov‐Like Radial Wake in Water Waves [PDF]
Advanced ScienceCherenkov radiation (CR) is a fascinating phenomenon that occurs not only in electromagnetic (EM) waves but also in water waves. The V‐shaped wake formed by a moving object on the water surface results from the constructive interference of water waves of

Impact of metal filings and acoustic waves on solar still performance [PDF]
Scientific ReportsThe current study investigates the parameters for improving the performance of a water stiller. The paper looks at two influencing factors. The first parameter is the effect of various metal filings at changing concentrations. The second parameter is the

Nonlinear evolution of water waves and their dispersion relation in coastal waters [PDF]
Theoretical and Applied Mechanics, 2023 Preliminary results of the derivation of a new phase-resolving (deterministic) spatio-temporal nonlinear model of water wave evolution in nondeep waters with constant bathymetry are presented in this paper. The model is the first of its kind to include a

Phase Evolution of the Time- and Space-Like Peregrine Breather in a Laboratory
Fluids, 2021 Coherent wave groups are not only characterized by the intrinsic shape of the wave packet, but also by the underlying phase evolution during the propagation.

Transformation of the Peregrine Breather Into Gray Solitons on a Vertically Sheared Current
Frontiers in Physics, 2021 In this Brief Research Report, we show, within the framework of the nonlinear Schrödinger equation in deep water and in the presence of vorticity (vor-NLS), that the Peregrine breather traveling at the free surface of a shear current of slowly varying ...

Pre-computation of image features for the classification of dynamic properties in breaking waves
European Journal of Remote Sensing, 2023 The use of convolutional neural networks (CNNs) in image classification has become the standard method of approaching many computer vision problems. Here we apply pre-trained networks to classify images of non-breaking, plunging and spilling breaking ...

Wave Height Distributions and Rogue Waves in the Eastern Mediterranean
Journal of Marine Science and Engineering, 2021 There is a lack of scientific knowledge about the physical sea characteristics of the eastern part of the Mediterranean Sea. The current work offers a comprehensive view of wave fields in southern Israel waters covering a period between January 2017 and ...
