摘要

．我们导出了在螺旋轨道上运动的相对论性电子辐射出的电磁波矢量势的解析表达式，近似地认为沿螺旋轨道的速度远大于垂直于轴的速度。根据这个表达式，我们证明了电磁波具有螺旋波前并带有角动量。

Spatial structure and angular momentum of electro-magnetic wave radiated from a relativistic electron moving on a spiral orbit

. We derive analytic expressions for the vector potential of electromagnetic wave radiated from a relativistic electron moving on a spiral orbit under an approximation that the velocity along the spiral orbit is much larger than that perpendicular to the axis. Based on this expression, we show that the electromagnetic wave has a spiral wave front and carries angular momentum.
