SOLITON PROPAGATION IN INHOMOGENEOUS MEDIA WITH SHARP BOUNDARIES

摘要

Thus, from the numerical experiments it is clearly seen that it is rather difficult to destroy the soliton structure. The soliton represents the corpuscle moving in the nonuniform medium. In the smoothly nonuniform medium the trajectory of the driving soliton is described by the usual geometrical optics. But on the boundaries of the media the combination of wave properties with the nonlinear focusing can result in unusual (compared with linear problems) behaviour of the trajectories. The soliton on the labile trajectory can not decide where it should go for a long time.
