Abstract: | We extend the multiple-scattering theory (MST) for elastic wave scattering and propagating in two-dimensional composite. The
formalism for the band structure calculation is presented by taking into account the full vector character of the elastic
wave. As a demonstration of application of the formalism we calculate the band structure of elastic wave propagating in a
two-dimensional periodic arrangement of cylinders. The results manifest that the MST shows great promise in complementing
the plane-wave (PW) approach for the study of elastic wave.
