%X The study of phononic crystals band gap will not only give rise to a new interesting theory,but also open up variety of possible application.The plane wave expansion method is introduced to calculate the band gap for two-dimensional solid phononic crystals with square lattices.The effects of different shapes of the scatterers’ section on band gaps are investigated.The calculated results show that when the scatterers’ filling fraction F<0.5,the circular section is easier to attain large band gaps than the square section and rectangle one;while when F>0.5,the square section is more favorable for the appearance of the band gaps.
