Magneto-Hydrodynamic Waves in a Plasma
Nature, 1950AT low frequencies transverse waves can be propagated through a conducting liquid, situated in a magnetic field, as was first shown by H. Alfven1 and verified by S. Lundquist2 in a laboratory experiment. The waves, as obtained by the reciprocal action between electric currents and motion of the liquid, were called magneto-hydrodynamic waves.

Excitation of plasma waves by electromagnetic waves in magnetized plasmas
Physics of Fluids B: Plasma Physics, 1993Three-dimensional equations for the plasma wake fields in the presence of a single frequency, intense circularly polarized electromagnetic (CPEM) wave in a two-component magnetoplasma are derived. For a given CPEM envelope, the axial electric fields of plasma waves are obtained for a one-dimensional model problem in which all the waves are aligned ...

Emission of plasma cyclotron waves in plasma-filled backward-wave oscillators
Physical Review Letters, 1990Grâce a la simulation numerique des oscillateurs a ondes regressives remplis de plasma on trouve qu'a l'interieur d'une certaine gamme de valeurs pour le champ magnetique, le taux de croissance de l'interaction cyclotron faisceau-plasma est significativement plus eleve que l'oscillation d'onde regressive ...

In the previous chapter we considered the quasi-static instabilities in the solid state plasma described by the continuity equations, equations of motion and expressions for the current density for each type of charged particles. The longitudinal quasi-static electric field caused by charge carriers oscillations has been determined by the Poisson ...

Plasma waves in a nonideal plasma
Journal of Experimental and Theoretical Physics, 1998This paper shows how the concepts commonly used for a Debye plasma—Landau damping, collisional damping, short-range and long-range collisions, and plasma waves—must be revised to describe a nonideal electron-ion plasma. The degrees of freedom of a nonideal plasma are divided into collective and individual. The increase and saturation of the fraction of

Wave-wave interactions in plasmas
AIP Conference Proceedings, 2009The interaction of large amplitude electromagnetic waves with plasmas is considered. We first show how a pump wave can excite sidebands and different types of low‐frequency electrostatic waves, and then derive dispersion relations which include three‐wave as well as four‐wave coupling mechanisms.

Plasma Wave Echo in a Weakly Turbulent Plasma
The Physics of Fluids, 1970The effects of turbulent fluctuations on the plasma wave echo have been investigated for a one-dimensional weakly turbulent electron plasma. It has been found that the interaction between electrons and fluctuations gives rise to (i) damping of the plasma echo, (ii) shift of the maximum position of plasma echo, and (iii) suppression of the peak ...

Any periodic motion of a fluid can be decomposed by Fourier analysis into a superposition of sinusoidal oscillations with different frequencies ω and wavelengths λ. A simple wave is any one of these components. When the oscillation amplitude is small, the waveform is generally sinusoidal; and there is only one component.

Since a plasma consists of light electrons and heavy ions, waves in plasmas are roughly divided into two : high frequency waves for which the electrons are carriers of the mass motion and low frequency waves whose dynamical motion is carried by the ions.
