Maximizing acoustic band gap in phononic crystals via topology optimization. The trend is that both the dispersion curve and the corresponding low group velocity move to the high frequency with the increase of 𝜃. It can be seen from the separated dispersion curve that acoustic waves of different frequencies propagate at different group velocities along the edge state.	cache/ajst-19146.pdf	txt/ajst-19146.txt
