SELF-GENERATED MAGNETIC FIELD BY HIGH FREQUENCY MODULATIONAL FIELD IN PLASMA
等离子体在高频调制场作用下形成自生磁场的机制

Magnetic field generated in plasma with high frequency modulational field has been studied in detail.By solving the two time-scale and two fluid equations,a set of nonlinear equations has been obtained by which the behavior of self-generated magnetic field can be described. Numerical results show that magnetic field self-generated by high frequency modulational field can be produced and with increase of time this magnetic field may collapse,leading to great enhancement of the magnetic field.
