On the relation between time-reversed acoustics and Green's function retrieval in space-variant and in time-variant materials
Kees Wapenaar, Johannes Aichele, Dirk-Jan van Manen
The methods of time-reversed acoustics and Green's function retrieval are traditionally deployed for classical inhomogeneous, time-invariant materials. The mutual relation between…

Broadband acoustic invisibility and illusions
Theodor S. Becker, Dirk-Jan van Manen, Thomas Haag +6
Rendering objects invisible to impinging acoustic waves (cloaking) and creating acoustic illusions (holography) has been attempted using active and passive approaches. While passiv…
