Space Science Reviews, 1991
Many significant wave phenomena have been discovered at Venus with the plasma wave instrument flow on the Pioneer Venus Orbiter. It has been shown that whistler-mode waves in the magnetosheath of the planet may be an important source of energy for the topside ionosphere.

The Physics of Fluids, 1960
The propagation of waves through a plasma, wherein the density and/or magnetic field strength are slowly varying functions of position is discussed. If the local propagation constant, kx, is a slowly varying function of x, the adiabatic approximation will be valid. However, kx2 may pass through zero as a function of x.

Transverse Plasma Waves and Plasma Vortices
Physical Review, 1958Plasmas at high-electron temperatures can carry transverse waves in which self-magnetic fields and relativistic effects become important. The relativistic perturbation equations for an isotropic uniform plasma are solved as an initial-value problem, i.e., by Laplace transformation and the propagation or dispersal of both longitudinal and transverse ...

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 ...

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 ...

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.

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.

Waves are basic manifestation of collective effects in plasmas. Wave types occurring in the plasma state are introduced and discussed with experimental applications, e.g. for the diagnostics of plasmas. This Chapter is fundamental to Part II and covers many aspect introductory to Chapters on applications (see Part III), e.g. on plasma diagnostics.
