Stabilization of linear ion beam right-hand polarized instabilities by nonlinear Alfvén/ion-cyclotron waves
(Blackwell Publishing Ltd, 2003)
It is shown that ion-beam plasma electromagnetic right-hand polarized instabilities can be stabilized by nonlinear left-hand polarized waves. This phenomenon constitutes a nonlinear saturation mechanism for right-hand ...
Investigations on the interactions between structural and aerodynamic nonlinearities and unsteadiness for aeroelastic systems
(2022-01-01)
A nonlinear analysis is performed on a two-degree-of-freedom wing-based system. Structural nonlinearities are introduced in the pitch degree of freedom when considering two different forms of the aerodynamic loads. Comparisons ...
Effect of a large-amplitude circularly polarized wave on linear beam-plasma electromagnetic instabilities
(Blackwell Publishing Ltd, 2003)
In a previous paper, sufficiently large-amplitude and left-handed ‘‘pump waves’’
propagating parallel to the background magnetic field were shown to stabilize a
moderately dense beam in a proton plasma against the ...
Modulation instability in waveguides with an arbitrary frequency-dependent nonlinear coefficient
(Optical Society of America, 2020-05)
In this Letter, we present, for the first time, to the best of our knowledge, the modulation instability (MI) gain spectrum of waveguides with an arbitrary frequency-dependent nonlinear coefficient ensuring strict energy ...
Narrowband and ultra-wideband modulation instability in nonlinear metamaterial waveguides
(Optical Society of America, 2020-11)
Waveguides based on metamaterials may exhibit strongly frequency-dependent nonlinearities. In this work, we focus on the phenomenon of modulation instability in this type of waveguide, departing from a new modeling equation ...
On the Secondary Instability of Forced and Unforced Laminar Separation Bubbles
(2015-01-01)
Previous studies demonstrate that the primary instability of laminar separation bubbles (LSB) on a flat-plate in the absence of external forcing is a three-dimensional centrifugal one. This work develops a weakly non-linear ...
Simple method for measuring dispersion and nonlinear coefficient near the zero-dispersion wavelength of optical fibers
(Ieee-inst Electrical Electronics Engineers IncNew YorkEUA, 1999)
Modulation instability in waveguides doped with anisotropic nanoparticles
(Optical Society of America, 2020-06)
We exploit the anisotropic plasmonic behavior of gold nanorods (AuNRs) to obtain a waveguide with a nonlinear coefficient dependent on both the frequency and polarization of incident light. The optical properties of the ...
Three-dimensional sand ripples as the product of vortex instability
(Elsevier Science IncNew YorkEUA, 2013)
Instability in nonlinear Schrödinger breathers
(Universidad Catolica del Norte, 2017)
We consider the focusing Nonlinear Schrödinger equation posed on the one dimensional line, with nonzero background condition at spatial infinity, given by a homogeneous plane wave. For this problem of physical interest, ...
