Abstract

Relativistic electromagnetic plasma waves are described by a dynamical equation that can be solved not only in terms of plane waves, but also for several different accelerating wavepacket solutions. Depending on the spatial and temporal dependence of the plasma frequency, different kinds of accelerating solutions can be obtained, for example, in terms of Airy or Weber functions. Also, we show that an arbitrary accelerated wavepacket solution is possible, for example, for a system with a luminal plasma slab.

相对论电磁等离子体波包的不同加速传播方式

相对论电磁等离子体波由一个动力学方程描述，该方程不仅可以根据平面波求解，还可以根据几种不同的加速波包求解。根据等离子体频率的空间和时间依赖性，可以得到不同类型的加速解，例如艾里函数或韦伯函数。此外，我们还证明了任意加速波包解也是可能的，例如，对于具有腔室等离子体板的系统。
