Experimental demonstration of asymmetric diffraction based on a passive parity-time-symmetric acoustic grating
Yuzhen Yang, Han Jia, Yafeng Bi +2
Passive parity-time-symmetric medium provides a feasible scheme to investigate non-Hermitian systems experimentally. Here, we design a passive PT-symmetric acoustic grating with a…

Experimental demonstration of three-dimensional broadband underwater acoustic carpet cloak
Yafeng Bi, Han Jia, Zhaoyong Sun +3
We present the design, architecture and detailed performance of a three-dimensional (3D) underwater acoustic carpet cloak (UACC). The proposed system of the 3D UACC is an octahedra…
