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

Figure 3

Dispersion curves for a single layer in frequency-wave number representation (a) and in phase velocity-frequency representation (b). Parts that are lacking in the phase velocity plot (b) correspond to wave numbers greater than the measured ones.
