非衍射电磁Airy脉冲的分岔轨迹
Bifurcating trajectory of non-diffractive electromagnetic Airy pulse
摘要：
从傍轴近似下的麦克斯韦方程组出发，导出了时空Airy脉冲的显式表达式。分析了脉冲在时空坐标系中的运动轨迹。的分歧点的存在，分离区域的脉冲传播的定性不同的功能证明。在这一点上，脉冲的速度变得无限大，其方向改变为相反。
英文摘要：
The explicit expression for spatial-temporal Airy pulse is derived from the Maxwell's equations in paraxial approximation. The trajectory of the pulse in the time-space coordinates is analysed. The existence of a bifurcation point that separates regions with qualitatively different features of the pulse propagation is demonstrated. At this point the velocity of the pulse becomes infinite and the orientation of it changes to the opposite.
