Calculation of the band structure for piezoelectric phonons based on the finite element software COMSOL Multiphysics is introduced in detail.The effects of different shunt circuits on the band structure of piezoelectric phonons are then discussed.Finally,some common errors that are easy to occur in energy band calculation are enumerated,and the corresponding solutions are given.

Key words: piezoelectric phononic crystal, shunt circuit, energy band structures, COMSOL Multiphysics
