Surface acoustic waves in interaction with a dislocation
(ELSEVIER, 2010)
A surface acoustic wave can interact with dislocations that are close to the surface. We characterize this
interaction and its manifestations as scattered surface acoustic waves for different orientations with
respect ...
Do electromagnetic waves always propagate along null geodesics?
(IOP Publishing Ltd, 2017)
We find exact solutions to Maxwell equations written in terms of fourvector potentials in non-rotating, as well as in Gdel and Kerr spacetimes. We show that Maxwell equations can be reduced to two uncoupled secondorder ...
A numerical method to solve a nonlocal dispersive wave system.
(2011-10-13)
We use a spectral method to solve numerically a generalization of an integro-differential system
proposed by Choi and Camassa [4] as a model to describe internal waves propagating at the
interface of two immiscible ...
Stationary shapes for 2-d water-waves and hydraulic jumps
(2016)
A hydraulic jump is a physical phenomenon commonly observed in nature such as in open channel flows or spillways and is dependent upon the relation between the initial upstream fluid speed and a critical speed characterized ...
Degeneration of internal Kelvin waves in a continuous twolayer stratification
(Cambridge Univ Press, 2015)
We explore the evolution of the gravest internal Kelvin wave in a two-layer rotating cylindrical
basin, using direct numerical simulations (DNS) with a hyperviscosity/diffusion approach to
illustrate different dynamic ...
Nonlinear Electrostatic Ion-Acoustic-Like Instabilities in a System with Two Streaming Ion Components Moving in a Background Plasma
(Bentham open, 2008-11-26)
Finite amplitude Alfvén-cyclotron waves are believed to play an important role in coronal heating and
nonthermal properties of velocity distribution functions. These effects are thought to be due to parametrically ...
A note on the wave equation for a class of constitutive relations for nonlinear elastic bodies that are not Green elastic
(Sage Publications, 2018)
A class of constitutive relations for elastic bodies has been proposed recently, where the linearized strain tensor is expressed as a nonlinear function of the stress tensor. Considering this new type of constitutive ...
Hysteretic Faraday waves
(American Physical Society, 2016)
We report on the numerical and theoretical study of the subcritical bifurcation of parametrically amplified waves appearing at the interface between two immiscible incompressible fluids when the layer of the lower fluid ...
Entrainment threshold of sand- to granule-sized sediments under waves
(Elsevier, 2015)
An improved method is presented to determine the threshold boundary velocity required to entrain sediments under waves, using the non-dimensional group settling velocity of sediments ranging from very fine sand to granules ...
Wave damping of a sloshing wave by an interacting turbulent vortex flow
(American Physical Society, 2020)
We report on the enhancement of the hydrodynamic damping of gravity waves at the surface of a fluid layer as they interact with a turbulent vortex flow in a sloshing experiment. Gravity surface waves are excited by oscillating ...
