Acoustic metasurfaces have shown remarkable capabilities for shaping acoustic wavefronts. However, most thin metamaterials can only work well for a narrow range of acoustic frequencies. This limitation has thus far dramatically limited their potentia

Noise is everywhere in our lives. Low-frequency noise in particular has a conspicuous if not disturbing presence since thicker materials are required to absorb or block it. Meanwhile, the very ubiquitousness of noise in our environment makes it a goo

Wave fields with acoustic orbital angular momentum have drawn greatattention because of its wide range of applications such as acoustic communication and particle manipulation. We designed, fabricated, and experimentally validated a type of lossy met

Since the radiation resistance of a vibrating membrane in the air is proportional to frequency in the subwavelength range, low frequency (

Breaking reciprocity is of fundamental importance in communication and signal processing and is less explored in the field of acoustics. Here, we show that non-reciprocal acoustic transmission can be realized in cascaded resonators that are periodica

We study the capabilities of time-modulated diffraction gratings as imaging devices. It is shown that a time-dependent but transversally homogeneous slab can be used to make a perfect image of an object in the far-field, since all the evanescent mode
