　　Recently.there has been a great interest in studying the wave propagation in a kind of artificial periodic composites named phononic crystals[1].This kind of composites exhibits the band gaps—frequency regions where propagation of acoustic or elastic waves is forbidden.The phononic crystals are expected to be applied in design of new sound shields, filters, transducers, refractive devices, etc.One of the key problems is the calculation of the band structures.
