The mode coupling arises from the interaction between the fundamental and the second-harmonic waves and permits modulational instability (MI) in the normal dispersion region under conditions where ...

The standing waves that produce the second, third and fourth harmonics etc, are exactly half, one third, and one quarter as long as the fundamental wave. But the standing waves aren't just related ...

The Fourier Series for a square wave, as shown in Figure 1, is [Ref 3]: The series has an infinite number of odd harmonics that combine to represent the square wave. Each higher harmonic is smaller in ...

For example, an unbalanced nonlinear wave distorts acutely as it travels and appears to ultimately fully lose its original shape, and in many instances the final outcome is onset of a form of ...
