Nonlinear Frequency Shift

Nonlinear effects for the electronic and ionic cyclotron modes propagating in the magnetosphere are studied by using the Vlasov equation; the frequency shift is deduced to the third order.Going to the case of a cold plasma for the whistler mode, we find that frequency shift vanishes, a result in agreement with Tidman and Stainer, based on the moments equations, but in contradiction with Watanabe's results derived from the Vlasov equation.For the hydromagnetic waves the effect does exist, but is not sufficient to explain the frequency–time displays ("sonagrams") of the so-called "pearl" events.

The excitation of the whistler mode waves propagating obliquely to the constant and uniform magnetic field in a warm and inhomogeneous plasma in the presence of an inhomogeneous beam of suprathermal electrons is studied. The full dispersion relation including electromagnetic effects is derived. In the electrostatic limit the expression for the growth rate is given. It is found that the inhomogeneities in both beam and plasma number densities affect the growth rates of the instabilities.

Nonlinear Frequency Shift

The problem concerning the appropriate form for the nonlinear frequency shift arising from slow density modulations of electrostatic surface waves in a semi-infinite unmagnetized plasma is reconsidered. The spatial dependence of the wave amplitude normal to the surface is kept general in order to allow for possible nonlinear attenuation behaviour of the surface waves. It is found that if the frequency shift is expressed as a function of the density and its gradient then the result is identical with that of Zhelyazkov (1987b), who assumed a linear exponential attenuation behaviour.
