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 finite difference migration, proposed and developed by J. F. Claerbout[1], is now widely used in seismic data processing. The method has a limitation that the events are not dipping too much.

Finite-Difference Time-Domain (FDTD) methods represent a cornerstone in the numerical simulation of wave propagation phenomena. These methods solve Maxwell’s equations directly in the time domain, ...

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 ...
