A Nonlinear Gradient-Coiling Metamaterial for Enhanced Acoustic Signal Sensing
Acoustic sensing systems play a critical role in identifying and determining weak sound sources in various fields. In many fault warning and environmental monitoring processes, sound-based sensing techniques are highly valued for their information-rich and non-contact advantages. However, noise sign...
