Pulse dynamics of flexural waves in transformed plates
Kun Tang, Chenni Xu, Sebastien Guenneau +1
Coordinate-transformation-inspired optical devices have been mostly examined in the continuous-wave regime: the performance of an invisibility cloak, which has been demonstrated fo…
CPA-Lasing in Thin-Elastic Plates via Exceptional Points
M. Farhat, P. Y. Chen, S. Guenneau +1
We present here how a coherent perfect absorber-laser (CPAL) enabled by parity-time ()-symmetry breaking may be exploited to build monochromatic amplifying devices fo…
Scattering Cancellation Technique for Acoustic Spinning Objects
Mohamed Farhat, Sebastien Guenneau, Andrea Alu +1
The scattering cancellation technique (SCT) has proved to be an effective way to render static objects invisible to electromagnetic and acoustic waves. However, rotating cylindrica…
Effective model for elastic waves propagating in a substrate supporting a dense array of plates/beams with flexural resonances
Jean-Jacques Marigo, Kim Pham, Agnès Maurel +1
We consider the effect of an array of plates or beams over a semi-infinite elastic ground on the propagation of elastic waves hitting the interface. The plates/beams are slender bo…
