Abstract
Finite difference (FD) simulations of wave propagation in acoustic media, subject to appropriate boundary conditions, continuous to be insightful and relevant for seismic modeling, room acoustics, electromagnetics, among others applications. Main reasons include their low computation times and satisfactory accuracy even for highly heterogeneous materials. Reductions of simulation times can be achieved by using implicit or semi-implicit time integrations that allow large CFL stepping, and accurac...
