1.9.3 The Rouge Waves

Rogue wave is one of the new form, large, unexpected and very dan-

gerous phenomena in nature. These waves have not been fully investigated
[74] and have only been accepted as a real phenomenon over the past few

decades. Rogue waves effect in large boats and ocean liners as shown in

Figs.(1.7-1.9) [67 ]. In the last few years, the rogue waves are important
in investigating oceans wave since their amplitude can reach two, three,

or even more many times the height of the surrounding waves [76].

Accordingly, the creation conditions and understanding features of this
wave could be very important and useful not only to avoid it but also

to generate very highly energetic pulses. On the other hand, this killer

wave appears in ocean [77] and many areas of physics i.e. optical fibers

[78-81], Bose-Einstein condensates, super-fluids, atmosphere, astrophys-
ical environments and plasma physics [82-90]. More specifically, rogue

waves are called mysterious waves (they appeared from nowhere and dis-

appeared without trace)[91-93]. Several theoretical studies on rogue waves

existence main mechanism have been done [94-97]. Also, soliton collisions
with an energy exchange can lead to the rogue wave creation [98, 99].
