Abstract: Realizing precise modulation of acoustic fields based on artificial structures and metasurfaces is currently a hot spot in the fields of physics and materials science. Compared to traditional natural materials, artificial structures offer significant advantages, including complex modulation, dimensional flexibility, and compact integration. With the ongoing advances in micro- and nano-fabrication technologies, such as 3-dimension printing, photolithography, laser cutting, and etching, it is now possible to achieve more precise and flexible control over the morphology and geometry of structural unit-cells. This provides many more means to achieve efficient and accurate modulation of acoustic fields. This article introduces several highly efficient, compact micro-nano artificial structures and devices, including the meta-grating-based acoustic tweezers, and super-hydrophobic ultra-thin lightweight acoustic devices. These innovations are anticipated to have diverse applications in the fields of ultrasonic imaging and therapy, as well as particle manipulation, due to their unique acoustic wave manipulation capabilities. Finally, we discuss the future trends and prospects of these structures for metamaterials and metasurface-based acoustic devices.
