Three-dimensional vector waves in time-variant materials, with applications in time-reversed focusing and Green's function retrieval
Kees Wapenaar, Dirk-Jan van Manen
The behavior of wave propagation and scattering in time-variant materials has been studied by many authors, for electromagnetic as well as for mechanical waves. Most studies consid…
Acoustic Cloning
Jonas Müller, Theodor S. Becker, Xun Li +4
Cloning refers to producing identical copies of existing objects. Here, we experimentally show how to clone acoustic scattering objects. We acquire a digital twin and bring it back…
Acoustic disguising: a unified framework for cloaking and holography
Jonas Müller, Dirk-Jan van Manen
Cloaking and holography -- usually treated as distinct problems -- are two limits of a single operation that we call acoustic disguising, realized here using immersive boundary con…
On acoustic space-time media that compute their own inverse
Dirk-Jan van Manen, Johannes Aichele, Jonas Müller +2
We derive time reflection and transmission coefficients for 1D acoustic waves encountering a time boundary at which the properties of the medium change instantaneously. The time re…
Waves in space-dependent and time-dependent materials: a systematic comparison
Kees Wapenaar, Johannes Aichele, Dirk-Jan van Manen
Waves in space-dependent and time-dependent materials obey similar wave equations, with interchanged time- and space-coordinates. However, since the causality conditions are the sa…
Binary classification of spoken words with passive phononic metamaterials
Tena Dubček, Daniel Moreno-Garcia, Thomas Haag +11
Mitigating the energy requirements of artificial intelligence requires novel physical substrates for computation. Phononic metamaterials have a vanishingly low power dissipation an…
