Time-domain finite-difference (TDFD) method is the most dominant approach for seismic wavefield simulation. Due to the memory and computational cost of the computer, finite-difference (FD) simulations ...

Finite difference is a simple and efficient mathematical tool that helps solve differential equations. In this paper, we solve an isotropic acoustic 3D wave equation using explicit, time domain finite ...

The scattering of an acoustic wave propagating in a non-uniform waveguide is inspected by revisiting improved multimodal methods in which the introduction of additional modes, so-called boundary modes ...

A research group has successfully developed a wave-based acoustics simulation that can make highly accurate time-domain estimations of acoustics in large-scale interior spaces (such as concert halls) ...

Typically, when a soundwave strikes a surface, it reflects back at the same fundamental frequency with a different amplitude. A new model shows that when a sound wave hits a nonlinear elastic ...

Previously it has been shown that all finite energy, causal solutions of the time-dependent three-dimensional acoustic equation and Maxwell's equations have forms for large radius that, except for a ...
