- 摘要：
- In this paper, we study the band gaps (BGs) of new proposed radial phononic crystal
(RPC) structure composed of multilayer sections. The band structure, transmission
spectra and eigenmode displacement fields of the multilayer RPC are calculated by
using finite element method (FEM). Due to the vibration coupling effects between thin
circular plate and intermediate mass, the RPC structure can exhibit large BGs, which
can be effectively shifted by changing the different geometry values. This study shows
that multilayer RPC can unfold larger and lower BGs than traditional phononic crystals
(PCs) and RPC can be composed of single material.
