The paper presents the theoretical foundation of wavefield extrapolation process in inhomogeneous medium with arbitrary variations of velocity. The matrix-like Neumann series in wavenumber and time domain is shown to be one of solutions to the wave equation. The approximation used in seismic migration to reduce the time consuming matrix operations is presented. The synthetic wavefields were used to demonstrate the properties of forward modeling and reverse-time migration.
