Ponderomotive Forces On Waves In Modulated Media
Authors: I.Y. Dodin and N.J. Fisch
Abstract: 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 fi eld. 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.
