Abstract
It is well known that a wave can generate other waves (due to
nonlinearity of continuous media). This talk is about a different
situation, when a wave suppresses other waves.
It is shown that a train of long waves can suppress a short-wave field
due to 4-wave resonance interactions. These interactions lead to the
diffusion (in the Fourier space) of the wave action of the short-wave
field, so that the wave action is transported to the regions of higher
wave numbers, where it dissipates more effectively.
