• The wave distortions caused by the dispersion to a rectangular wave are calculated by a method based on an approximation by a Fourier series expansion and the distinctive features of their dispersive waves are shown. Next, for the case that the rectangular wave is given to the free end of a cantilever, both the results of the dispersive waves according to the finite element model and the experimental results coincide with the ones approximated by Fourier expansion. From these results, it is clear that the wave distortions arise actually. A study of the forming process of the natural modes leads to the conclusion that the modes of higher frequencies are early formed.
