Efficient time-domain eccentric model for Galactic binaries in LISA
Shubhanshu Tiwari, Johan O. A. Robertsson, A. Gopakumar +4
Galactic binaries are expected to be the most numerous long-lived sources in the Laser Interferometer Space Antenna (LISA) data stream and are commonly modeled as quasi-circular, n…
Ground-to-Cable Strain Transfer in Unburied DAS on Earth and the Moon
Simone Probst, Marc Serra Garcia, Olav Cornelius +2
Distributed acoustic sensing (DAS) cables are typically buried to ensure good coupling and reduce unwanted atmospheric noise. Unburied deployments are attractive for rapid response…
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…
Efficient wave type fingerprinting and filtering by six-component polarization analysis
David Sollberger, Nicholas Bradley, Pascal Edme +1
We present a technique to automatically classify the wave type of seismic phases that are recorded on a single six-component recording station (measuring both three components of t…
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…
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…
Finite-difference modeling of 2-D wave propagation in the vicinity of dipping interfaces: a comparison of anti-aliasing and equivalent medium approaches
Erik F. M. Koene, Jens Wittsten, Johan O. A. Robertsson
Finite-difference (FD) modeling of seismic waves in the vicinity of dipping interfaces gives rise to artifacts. Examples are phase and amplitude errors, as well as staircase diffra…
Removing numerical dispersion from linear evolution equations
Jens Wittsten, Erik F. M. Koene, Fredrik Andersson +1
We describe a method for removing the numerical errors in the modeling of linear evolution equations that are caused by approximating the time derivative by a finite difference ope…
Perfect partial reconstructions for multiple simultaneous sources
Jens Wittsten, Fredrik Andersson, Johan Robertsson +1
A major focus of research in the seismic industry of the past two decades has been the acquisition and subsequent separation of seismic data using multiple sources fired simultaneo…
Numerical analysis of the lattice Boltzmann method for simulation of linear acoustic waves
Dattaraj B. Dhuri, Shravan M. Hanasoge, Prasad Perlekar +1
We analyse a linear lattice Boltzmann (LB) formulation for simulation of linear acoustic wave propagation in heterogeneous media. We employ the single-relaxation-time Bhatnagar-Gro…
