Abstract
The finite difference time domain method for numerical simulation of two-dimensional solid gas Affirmative phononic crystals bandgap characteristics based on the structure, filling rate and the lattice constant influence on the band gap characteristics of the calculation, the formation of the band gap filling rate at f=0.8, the research conclusions provide theoretical basis for structure design of phononic crystals.
