Presentation title: Acoustic metamaterials for sound manipulation and beyond
Abstract: Recent years, the acoustic metamaterial has some special acoustic properties in natural materials, which have opened new ways to achieve magic acoustic phenomena, such as asymmetric sound manipulation and high-quality acoustical holography. The acoustic metamaterials also provide a new route for breaking through the fundamental limitation of traditional acoustic theory and technology. However, they are mainly used for specific waves manipulation, and difficult to realize acoustic detection, imaging and others independently. To solve these problems, the brain-like intelligent system is built by acoustic artificial structure. a specific matrix is designed on the basis of deep-learning techniques. It is verified that the groups of metamaterial unit-cells with specific matrix have specific intelligence for desired tasks. Taking the object identification based on the scattered wave as an example, which is of fundamental significance in wave physics, the meta-neural-network exhibits its magic performances in completing complex tasks with simplicity, precision, real time, and pure passivity.
