Summary:

Two dimensional multi-atom Archimedean-like phononic crystals (MAPCs) can be
obtained by adding “atoms” at suitable positions in primitive cells of traditional simple
lattices. Band structures of solid-solid and solid-air MAPCs are computed by the finite
element method in conjunction with the Bloch theory. For the solid-solid system, our
results show that the MAPCs can be suitably designed to split and shift band gaps
of the corresponding traditional simple phononic crystal (i.e., with only one scatterer
inside a primitive cell). For the solid-air system, the MAPCs have more and wider band
gaps than the corresponding traditional simple phononic crystal. Numerical calculations
for both solid-solid and solid-air MAPCs show that the band gap of traditional simple
phononic crystal can be tuned by appropriately adding “atoms” into its primitive cell.
