title = "Evolution of Gaussian packets in inhomogeneous media",
abstract = "Time-dependent Gaussian Packets are high-frequency asymptotic space-time particle-like solutions of the wave equation. A Gaussian Packet is a Gaussian shape timelocalized Gaussian Beam. We study the dependence of Packet shape to the initial values and discuss the evolution of Gaussian Packet in smooth media and strong inhomogeneous media. Through comparison between paraxial Gaussian Packets and the results from finite difference simulations in strongly inhomogeneous media, such as the SEG/EAGE salt model, we see the severe deviation of paraxial Gaussian Packet from the accurate solution at large propagation time and near the salt boundaries. The application to strongly heterogeneous media needs to be further studied.",
