Dependence of dispersion curves of acoustic wave propagation in the infinite periodic lattice of a 5 × 5 unit cell as a function of the mass value (a) mass of inclusion material aluminum malu = 8 × 10−2 kg and mass of host matrix epoxy mepoxy = 1.82 × 10−2 kg; (b) mass of inclusion material aluminum malu = 10 × 10−2 kg and mass of host matrix epoxy mepoxy = 1.82 × 10−2 kg; (c) mass of inclusion material aluminum malu = 15 × 10−2 kg and mass of host matrix epoxy mepoxy = 1.82 × 10−2 kg.
