Wave-particle interaction at double resonance

Physical Review E, 2008
This paper is devoted to studying wave-particle interaction at "double resonance" condition, i.e., when two waves interact resonantly with the same group of charged particles. A theoretical Hamiltonian model and a symplectic numerical code are built to describe the three-dimensional interactions of wave spectra with resonant electrons in a magnetized ...

Wave–Particles Interaction

2014
AbstractIn this Chapter an alternative derivation of the self-consistent Vlasov-Maxwell equations for wave-particles interaction is given. The analysis is carried out under a rigorous Hamiltonian framework and targeted to modeling the dynamics of the Free Electron Laser.

Wave-Particle Interactions

1984
Note: Magnetospheric studies of the interactions between plasma waves and particles have generally been performed using Gaussian units. To allow the material presented here to be conveniently used in conjunction with other published material on magnetospheric wave-particle interactions, we have not converted equations from the literature into MKS units.

Wave–Particle and Wave–Wave Interactions

2012
In Chap. 3 we have discussed how plasma responds to an external (weak) electromagnetic perturbation, which results in a specific wave dispersion and damping. This damping is linear, i.e., proportional to the wave amplitude and there is no change in the plasma distribution function other than small oscillations proportional to the wave amplitude ...

VLF wave amplification by wave-particle interaction

Physics Letters A, 1971
Abstract A charged particle beam is assumed to move through the magnetosphere. It is shown that the VLF waves propagating at non-zero angles with the beam are amplified.

Convection and wave-particle interactions

Journal of Atmospheric and Terrestrial Physics, 1978
Abstract We study, by means of the adiabatic invariants and Liouville's theorem, the deformation of the distribution functions of substorm injected particles in the magnetosphere. Assuming a steady-state convection process, we can obtain simple analytical expressions for the particle flux, the anisotropy and the growth rate of electromagnetic ...

Models of Resonant Wave‐Particle Interactions

Journal of Geophysical Research: Space Physics, 2021
AbstractRadiation belt electrons are strongly affected by resonant interactions with cyclotron‐resonant waves. For broad band, small amplitude waves the interactions are well described by quasi‐linear diffusion in pitch angle and energy, but coherent, large amplitude waves such as strong whistler mode chorus call for a different treatment. The standard

Nonlinear wave-particle interaction in electrostatic waves

The Physics of Fluids, 1974
The unidimensional nonlinear Vlasov equation for electrostatic waves is consistently treated by a perturbation analysis in x-t space, without the usual approximation of small growth or damping rates. This analysis is correct through third-order terms in the field wave amplitude, and it includes the free streaming terms.

Relativistic structure of stochastic wave–particle interaction

The Physics of Fluids, 1988
Stochastic interactions of charged particles with electrostatic waves propagating at arbitrary angles to an external magnetic field are studied based on a relativistic canonical Hamiltonian formalism. The present theory, however, is valid also for electromagnetic waves after a slight modification.

Nonresonant Wave-coupling and Wave-particle Interactions

Physica Scripta, 1976
We study the interaction between two primary waves and their corresponding nonresonant beatwave. The beatwave is assumed to interact strongly with the plasma particles, thus causing a heating of the plasma and an energy transfer between the primary waves.
