Waves 2026 Book of Abstracts
Lise-Marie Imbert-Gerard, Chrysoula Tsogka, Daniel Appelo +4
WAVES 2026, 17th International Conference on Mathematical and Numerical Aspects of Wave Propagation Concordia University (John Molson Building), Montreal, Canada, June 22-26, 2026…
Discretization in Multilayered Media with High Contrasts: Is It All About the Boundaries?
Camille Carvalho, Stéphanie Chaillat, Elsie Cortes +1
Wave propagation in multilayered media with high material contrasts poses significant numerical challenges, as large variations in wavenumbers lead to strong reflections and comple…
Staggered explicit-implicit time-discretization for elastodynamics with dissipative internal variables
Tomáš Roubíček, Chrysoula Tsogka
An extension of the two-step staggered time discretization of linear elastodynamics in stress-velocity form to systems involving internal variables subjected to a possibly non-line…
Explicit time-discretisation of elastodynamics with some inelastic processes at small strains
Tomas Roubicek, Christos Panagiotopoulos, Chrysoula Tsogka
The 2-step staggered (also called leap-frog) time discretisation of linear 2nd-order Hamiltonian systems (typically linear elastodynamics in a stress-velocity form) is extended for…
Robust multifrequency imaging with MUSIC
Miguel Moscoso, Alexei Novikov, George Papanicolaou +1
In this paper, we study the MUltiple SIgnal Classification (MUSIC) algorithm often used to image small targets when multiple measurement vectors are available. We show that this al…
A quantitative study of source imaging in random waveguides
Liliana Borcea, Josselin Garnier, Chrysoula Tsogka
We present a quantitative study of coherent array imaging of remote sources in randomly perturbed waveguides with bounded cross-section. We study how long range cumulative scatteri…
