Transmission coefficients calculated for different systems: (a) a single 2 mm thick plate: Lamb wave modes appear very clearly, (b) graphical superposition for a single 2 mm thick plate and for a 3 mm thick plate: each plate has its own Lamb wave modes, (c) two plates (2 mm thick and 3 mm thick): there is a global Lamb wave mode filtering.
