Proof of concept for an ultrasensitive meta-device to detect and localize nonlinear elastic sources
Marco Miniaci, Antonio S. Gliozzi, Bruno Morvan +4
The appearance of nonlinear effects in elastic wave propagation is one of the most reliable and sensitive indicators of the onset of material damage. However, these effects are usu…
