Nonlinear programming analysis of multi-mode wave propagating characteristics in ion-beam plasma system
Abstract
Propagating characteristics of multimode waves are analyzed in an ion-beam plasma system by means of nonlinear programming techniques. A fine structure of each wave mode such as a wavenumber, damping rate, a wave amplitude, a wave peak point, and a phase relation among the waves is obtained from the observed interferometer traces of multimode waves. The wave pattern assembled with the separated patterns into each wave mode is confirmed to be quite similar to the observed one. A qualitative agreement of wave dispersion relation is obtained between the values analyzed by the present method and calculated by the plasma kinetic theory.
