Damping effects on parametric decays of Alfvén waves
(2001)
It is shown that damping effects can destabilize regions that are stable under non-dissipative fluid theory. Damping effects on the ion-acoustic modes are simulated by a collisional-like term in the longitudinal component ...
Ion acoustic damping effects on parametric decays of Alfvén waves: Right-hand polarization
(Blackwell Publishing Ltd, 2001)
We study ion acoustic damping effects on parametric decays of right-hand-polarized electromagnetic waves. We do this because ion beams have been observed in a variety of space environments, and consequently, these waves ...
Anti-Stokes Raman gain enabled by modulation instability in mid-IR waveguides
(Optical Society of America, 2018-11)
The inclusion of self-steepening in the linear stability analysis of modulation instability (MI) leads to a powercutoff above which the MI gain vanishes. Under these conditions, MI in mid-IR waveguides is shown to give ...
A quasi-periodic route to chaos in a parametrically driven nonlinear medium
(Elsevier, 2021)
Small-sized systems exhibit a finite number of routes to chaos. However, in extended systems, not all routes to complex spatiotemporal behavior have been fully explored. Starting from the sine-Gordon model of parametrically ...
Localised structures and pattern formation in heterogeneous nonlinear systems
(2018)
We investigate remarkable phenomena in nonlinear systems associated with intrinsically non-linear heterogeneities, motivated by real-world situations. We study the nonlinear dynamics in parametrically driven systems and ...
Localized waves in a parametrically driven magnetic nanowire
(EPL ASSOCIATION, EUROPEAN PHYSICAL SOCIETY, 2012-02)
The pattern formation in a magnetic wire forced by a transversal uniform and oscillatory magnetic field is studied. This system is described in the continuous framework by the Landau-Lifshitz-Gilbert equation. We find ...
A geometrical view of scalar modulation instability in optical fibers
(IEEE Photonics Society, 2017-09)
Full models of scalar modulation instability (MI) in optical fibers available in the literature usually involve complex formulations. In this paper, we present a novel approach to the analysis of MI in optical fibers by ...

Active flutter suppression in a 2-D airfoil using linear matrix inequalities techniques
(2006-01-01)
Flutter is an in-flight vibration of flexible structures caused by energy in the airstream absorbed by the lifting surface. This aeroelastic phenomenon is a problem of considerable interest in the aeronautic industry, ...
