The narrow attenuation bands of traditional marine structures have long been a challenge in mitigating water waves.In this paper,a metastructure(MS)composed of floating periodic pontoons is proposed for broadband wate...
The objective of this paper is to present a new method for designing absorbing or non-reflective boundary conditions (ABC) or (NRBC), illustrated by the case study of the modelling of a solid body in water, specifical...

In this paper,we focus on the state and parameter identification problem of a hydrodynamical system.This system is modeled as a linearized water wave equation(LWWE),a hyperbolic state-space model coupled with a Laplac...
A novel technique,named auxiliary equation method,is applied in this research work for obtaining new traveling wave solutions for two interesting proposed systems:the Kaup-Boussinesq system and generalized Hirota-Sats...

In this work, computational fluid dynamics (CFD)—based simulations and linear diffraction analysis are carried out to investigate the interaction between water waves and metamaterials composed of an array of C-shaped...
When water,light or sound waves impinge on objects smaller than the wavelength,a scattering process takes place[1].The scattering of waves plays an essential role in a myriad of natural phenomena.In ocean engineering,...
Since the discovery of generalized Snell’s law in 2011[1],metasurfaces have opened up the mainstream of arbitrary wavefront manipulation in electromagnetism.Using a gradient-index metasurface,the parallel wavenumber ...
