Title:

An Extended K-dV Equation for Nonlinear Magnetosonic Wave in a Multi-Ion Plasma

Date of publication:

1995

Key words:

Magnetosonic wave, Multi-ion species, Finite cut-off, Extended K-dV

Abstract:

Nonlinear magnetosonic waves propagating perpendicularly to a magnetic field are studied in two-ion plasma. It is shown that high frequency magnetosonic wave under the imfluence of finite cut-off frequency is described by an extended k-dV equation, rather than conventional K-dV equation. Modulational stability of this mode is strongly affected by the finite cut-off frequency in two-ion plasma.
