All-pass phase shifting achieved by acoustic unidirectional guided resonances
Applied Physics Express, 2023 Phase manipulation of sound is an important function for many acoustic applications. Here, we apply temporal coupled mode theory to demonstrate that sound all-pass phase shifting, which means that acoustic waves propagate with unit amplitude but have ...

Homogeneous material based acoustic concentrators and rotators with linear coordinate transformation
Scientific Reports, 2021 With the ability to focus and rotate the acoustic field in a given region while keeping the outside region unchanged, the acoustic concentrator and rotator has been developed for the versatile manipulations of acoustic wave. In this letter, we report the
