Guided waves were propagated in four plates with a sinusoidal-shaped surface. The functions defining surface shape differed only in phase shift, which forced the thickness distribution variability. On one hand, the smooth sine shape provided thickness variability and allowed for analysis of its influence on wave propagation velocity.

Sine waves produce a very 'smooth' welding arc, but it is sometimes beneficial to alter this basic waveform. Square waves were the first alternative for the sine wave. The area inside the graph of the waveform …
A sine wave or sinusoidal wave is the most natural representation of how many things in nature change state. A sine wave shows how the amplitude of a variable changes with time. The variable could be audible sound for example. A single pure note is a sine wave, although it would sound a very plain and flat note indeed with none of the harmonics we normally hear in nature.

The wave must therefore moving in a direction such that a short time later the displacement will rise. Looking at the snapshot of the wave in graph C, we see that the direction we need to shift the wave form such that the displacement immediately starts going up is the (-x)-direction. The wave must therefore be moving in that direction.
