Pseudo-Hermitian Systems Constructed by Transformation Optics with Robustly Balanced Loss and Gain
Liyou Luo, Jie Luo, Hongchen Chu +1
Non-Hermitian systems with parity-time symmetry have been found to exhibit real spectra of eigenvalues, indicating a balance between the loss and gain. However, such a balance is n…

Bidirectional acoustic negative refraction based on a pair of metasurfaces with both local and global PT-symmetries
Jun Lan, Xiaowei Zhang, Liwei Wang +2
Negative refraction plays an important role in acoustic wave manipulation and imaging. However, conventional systems based on acoustic metamaterials suffer from the limits induced…

Three-dimensional acoustic double-zero-index medium with a Dirac-like point
Changqing Xu, Guancong Ma, Ze-Guo Chen +4
We report a design and experimental realization of a three-dimensional (3D) acoustic double-zero-index medium (DZIM), whose effective mass density and compressibility are nearly ze…
