Feasibility Study of Printing Acoustic Metamaterials Using Extrsuion Freeforming Method

Metamaterial is a new field of research in engineered material which lately becomes object of interest due to its unique properties not found in natural objects. Properties such as bandgaps, wave guiding, cloaking and diffuser have been attractive research topics. In this paper, feasibility of using...
