摘要：

The existence of surface states for sonic propagation in elastic band gap finite periodic systems is shown in this Letter. These surface states slide and propagate the sound along the surface edges as whispering galleries. We also experimentally observe such surface modes as well as localization phenomena in linear and point defects. [S0031-9007(99)08907-3].
