摘要：

The frequency omega versus wave vector k of elastic waves propagating in periodic binary composites consisting of solid inclusions placed periodically in a host matrix was calculated. Attention was focused on the possibility of stop bands (spectral gaps) for all directions of propagation in such composites. It was fo;nd that gold or lead inclusions of about 10% volume fraction in a Si or Be matrix give rise to stop bands.
