NONLINEAR COUPLING OF THE ELECTROSTATIC DRIFT WAVE AND SHEAR ALFVEN WAVE IN MAGNETIZED PLASMAS
磁化等离子体中静电漂移波和剪切阿耳芬波的非线性耦合

In terms of Hasegawa-Wakatani equations,the nonlinear coupling of the electrostatic drift wave and the shear Alfven wave in magnetized plasmas has been investigated. The dipolar vortex solutions of the nonlinear equation system are obtained. These solutions belong to the intrinsic electromagnetic vortices, the corresponding magnetic field perturbations and the longitudinal current are continuous on the boundary of the vortex.
