Floquet-Bloch Theory and Its Application to the Dispersion Curves of Nonperiodic Layered Systems

Figure 4

Dispersion curves in representation obtained with padded signals (a). Zoom of the box marked in the left plot and the fast Fourier transform of the box function used for padding the signals (b). The distance between zeros of the obtained sinc function is , where is the spatial sampled rate and is the number of measured points.
