Abstract
Artificial micro-structures can be employed to modulate the sound source radiation and the propagation of acoustic waves. With the development of advanced 3D printing and micro-nano fabrication technologies, ultra-thin planar acoustic artificial structures have opened up new opportunities for the generation and manipulation of specially configured acoustic fields, and have become a hot research topic in the field of acoustic metamaterials. Delicate design of artificial structures enables the realization of various useful functionalities such as super-resolution acoustic imaging and high-fidelity holography, which hold promising applications in ultrasonic medical engineering, non-destructive testing and other related fields. This report presents the research progress in my lab, focusing on the fundamental principles of acoustic nano-micro metasurfaces, superhydrophobic micro-nano metasurface based echo imaging devices, micropore array based holographic devices, and the flexible metasurface devices for neuromodulation therapy.
