带电粒子在外加电磁场中去捕获问题

The Detrapping of Charged Particle under Electromagnetic Wave

带电粒子与电磁场相互作用过程中的去捕获问题对于等离子体物理学、带电粒子加速以及微波电子学等领域具有重要的意义。使用解析法研究了带电粒子的去捕获问题,并且对粒子的引导中心方程作了数值模拟。论文结果表明带电粒子的振动频率与电磁波频率发生共振时去捕获成为可能。

The detrapping of charged particle under electromagnetic wave has fundamental importance in plasma physics, charged particle acceleration. It is studied by analytical methods, and the equation of the guiding center is presented by numerical simulations. The results show that the interaction process can be considered as the resonance between the bounce frequency of the trapped particle and the frequency of the electromagnetic field.
