Bidirectional acoustic negative refraction based on a pair of metasurfaces with both local and global PT-symmetries

Negative refraction plays an important role in acoustic wave manipulation and imaging. However, conventional systems based on acoustic metamaterials suffer from the limits induced by loss-related and resolution issues. In this work, a parity-time (PT)-symmetric system is introduced to realize loss-f...
