Study on Asymmetric Diffraction of Acoustic Parity-Time-Symmetric Gratings Using Rigorous Coupled-Wave Analysis
Yuzhen Yang, Han Jia, Jun Yang
In PT-symmetric gratings, asymmetric diffraction can be generated by modulating the ratio between imaginary and real refractive indices. In this paper, a rigorous coupled-wave anal…

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…

Design of an impedance matching acoustic bend
Yuzhen Yang, Han Jia, Wenjia Lu +2
We propose the design of an impedance matching acoustic bend in this article. The bending structure is composed of sub-wavelength unit cells with perforated plates and side pipes,…
