Phononic crystal structure with a negative refractive index is able to produce a planar acoustic lens having high resolution. As for the condition that phononic crystal structure has a negative refractive index toward, it is determined by the lattices spacing of the phononic crystal, a radius of lattice, and sound velocity of around media. In this report, the influence by structure parameters of phononic crystal to a refractive index of the planer acoustic lens constructed with phononic crystal is described. Furthermore, the influence by structure parameters of phononic crystal to the focusing sound field by planar lens is examined by numerical analysis. |
