Development and Application of Acoustic Metamaterials with Locally Resonant Microstructures

Abstract

The purpose of this research is to design, fabricate, and study new acoustic metamaterials with a negative effective mass density and modulus. Through this study, it is anticipated that the implications to material and structural applications of the negative effective mass and modulus of metamaterials can be fully understood. Moreover, more microstructures for metamaterials will be designed and studied. The 3D printing technology will be utilized to produce these complicated microstructures and metamaterial specimens for experiments.
