| 内容記述 | The studies on the linear and nonlinear interactions between the electromagnetic waves and plasmas are of importance in order to understand the basic processes in the laser-pellet interaction, heating of magnetically confined plasma, and ionospheric modification. In the present thesis are described the nonlinear interactions associated with the parametric and modulational instabilities, and ponderomotive force. The high frequency electromagnetic field inside a resonant cavity is applied to the quiescent plasma, which is produced by the Lisitano coil at the electron cyclotron resonance. The experimental conditions, where each nonlinear phenomenon is dominant, are obtained by adjusting the pump and electron plasma frequencies. After the parametric decay of one pump field into the Langmuir and ion acoustic waves is studied, the double resonance parametric instability is experimentally confirmed for two pump fields, which have the frequency difference of twice the ion acoustic wave frequency. The modulational instability of the electron plasma wave is studied, comparing the experimental results with a theory. It is based on the coupling of the nonlinear schrödinger equation with the equation of the ion acoustic wave including the ponderomotive force. An experiment, in which the ponderomotive force is dominant, is carried out by using the electromagnetic wave with the higher frequency than the electron plasma frequency. The results obtained to confirm the ponderomotive force are extended to the experiments for suppressing the end loss of the mirror-confined plasma, and stabilizing the drift-cyclotron loss-cone instability. | |||||
