Higher-order Hamilton–Jacobi perturbation theory for anisotropic heterogeneous media: dynamic ray tracing in Cartesian coordinates
Iversen, Einar; Ursin, Bjørn; Saksala, Teemu; Ilmavirta, Joonas; de Hoop, Maarten (Journal article; Peer reviewed, 2019)With a Hamilton–Jacobi equation in Cartesian coordinates as a starting point, it is common to use a system of ordinary differential equations describing the continuation of first-order derivatives of phase-space perturbations ... -
How to adapt numerical simulation of wave propagation and ultrasonic laboratory experiments to be comparable — A case study for a complex topographic model
Solymosi, Bence; Favretto-Cristini, Nathalie; Monteiller, Vadim; Komatitsch, Dimitri; Cristini, Paul; Arntsen, Børge; Ursin, Bjørn (Journal article; Peer reviewed, 2018)Numerical methods are widely used in seismic exploration to simulate wave propagation; however, the algorithms are based on various assumptions. The accuracy of numerical simulations is of particular interest in the case ... -
