    Three-dimensional modulation of electron-cyclotron waves (1986)
    [S.l.] : American Institute of Physics (AIP)
    Physics of Fluids 29 (1986), S. 2479-2483 
    Details
    ISSN: 1089-7666
    Source: AIP Digital Archive
    Topics: Physics
    Notes: A set of nonlinear mode coupling equations, describing the interaction of large amplitude electron-cyclotron waves with low-frequency electrostatic as well as electromagnetic fluctuations, is presented. Accounting for the contributions of the ponderomotive force and relativistic electron mass variation nonlinearities, a general dispersion relation has been obtained for the parametric processes. Modulation and filamentation instabilities are investigated.

    Large amplitude ion-acoustic double layers in a double Maxwellian electron plasma (1986)
    [S.l.] : American Institute of Physics (AIP)
    Physics of Fluids 29 (1986), S. 3214-3218 
    Details
    ISSN: 1089-7666

    Topics: Physics
    Notes: A finite amplitude theory for an ion-acoustic double layer (DL) in a plasma with cold ions and two distinct groups of Boltzmann–Maxwellian distributed hot electrons is presented. Conditions are obtained under which large amplitude stationary double layers can exist. For physical parameters of interest, the DL profiles and the relationship between the maximum DL amplitude and the Mach number are found. A perturbation technique is introduced to derive a modified Korteweg–de Vries (MKdV) equation which governs the dynamics of a weak double layer. It is found that the parameter regimes for the existence of small and finite amplitude DL are not complementary to each other. The relevance of this investigation to space and laboratory plasmas is pointed out.

    Non-neutral whistler envelope solitons (1986)
    [S.l.] : American Institute of Physics (AIP)
    Physics of Fluids 29 (1986), S. 3488-3490 
    Details
    ISSN: 1089-7666
    Source: AIP Digital Archive
    Topics: Physics
    Notes: Whistler envelope solitons are reconsidered including the charge separation effects in the dynamics of quasistatic plasma slow response. The coupled nonlinear ordinary differential equations are solved with the help of a perturbation scheme in which the slow ambipolar potential is expanded in terms of the whistler wave intensity. The soliton profiles are obtained analytically.

    Electrostatic interchange modes with finite parallel wavelengths (1986)
    [S.l.] : American Institute of Physics (AIP)
    Physics of Fluids 29 (1986), S. 1488-1490 
    Details
    ISSN: 1089-7666
    Source: AIP Digital Archive
    Topics: Physics
    Notes: A set of nonlinear equations is derived that includes the parallel electron dynamics in the study of the electrostatic interchange instability. In the linear limit, interchange modes are coupled with drift-modified convective cell modes. It is shown that a pressure gradient as well as a nonuniform magnetic field can induce a new class of instabilities.
