【Abstract】

<正>In this paper we study the bandgap properties of three-dimensional holey phononic crystals with resonators using the finite element method.Complete bandgap can be obtained by the careful design of the geometry of the holes to generate the local resonance of the unit cell.The influence of the geometry parameters on the
