调制介质中波的有质动力
Ponderomotive forces on waves in modulated media
摘要：
通过瞬时交叉相位调制的波的非线性相互作用可以以与高频电磁场中的有质动力波-粒子相互作用相同的方式被投射。当探测波的射线散射由第二调制波产生的下层介质的扰动时，就像带电粒子散射准周期场一样，有质动力效应出现。与点粒子动力学相似，它本身也被这个理论推广，导致了波操纵的新方法，包括光的不对称障碍。
英文摘要：
Nonlinear interactions of waves via instantaneous cross-phase modulation can be cast in the same way as ponderomotive wave-particle interactions in high-frequency electromagnetic field. The ponderomotive effect arises when rays of a probe wave scatter off perturbations of the underlying medium produced by a second, modulation wave, much like charged particles scatter off a quasiperiodic field. Parallels with the point-particle dynamics, which itself is generalized by this theory, lead to new methods of wave manipulation, including asymmetric barriers for light.
