	<span style=\"font-family:Verdana;\">This study proposes a novel phononic-crystal acoustic
wave device (AWD). A graphene atomic structure was adopted as the
main research subject, and a graphene-like structure was designed using
piezoelectric material ZnO and its periodic boundary conditions were defined
using the finite element method (FEM). The study conducts acoustic-wave propagation
analysis in the frequency domain on the 2D graphene-like structure according to
Bloch theory to understand the band gap effects generated by its natural
vibration. The effects of shape transformation from a hexagonal honeycomb
structure into a regular polygon were also investigated regarding the band gap
phenomenon. Thus, this study compared and analyzed numerous 2D polygonal
graphene-like structures with a fixed bond diameter (d = 2R =0.7 mm), bonding stick width (0.2 mm),
and side length (1 mm), and
observed the trends of the band gap changes under natural vibration for designing
an optimal AWD; the studied 2D polygonal models were a square, and a regular
hexagon, octagon, and decagon.</span>
