Abstract: Acoustic metamaterials are novel artificial materials that can be designed to possess negative mess density and modulus.Realization of such materials not only leads to conceptual advancements in the fundamental theory of acoustics,but also enables possibilities for the investigation of various kinds of novel properties.This in turn provides the foundation for designing a variety of novel wave-functional applications.Acoustic metamaterials have attracted enormous interests in recent years.In this paper the author presents an overview of the progress in the research on acoustic metamaterials and gives an illustration to the locally resonant mechanism for realizing negative material parameters.

Key words: metamaterials, local resonance, negative-parameter-materials
