“…In recent years, researchers have made a significant progress in the development of calculation methods to analyze the band gap structure of phononic crystals. At present, the commonly used methods are: plane wave expansion method (PWE) (Zuo et al, 2022), lumped mass method (Kong et al, 2023), finite difference time domain (FDTD) method (Cao et al, 2004), finite element method (FEM) (Lu et al, 2022). As a mature method for numerical simulation of mechanical systems, the finite element method has a worked well with periodic structures and has also been successfully applied to the calculation of one-, two-and three-dimensional structures.…”

In this paper, a piezoelectric phononic crystal beam at the nanoscale has been mechanically modeled by using the surface piezoelectric theory. The band gap has been calculated by the plane wave expansion method and the band gap structure picture has been analyzed. The influence of electromechanical coupling effects, surface effects and geometry on the band gap properties are discussed separately. This study contributes positively to the design and active control of nanoelectromechanical systems.
