Fourier pseudo spectral method for attenuative simulation with fractional Laplacian

Fourier pseudo spectral method for attenuative simulation with fractional Laplacian

Pengliang Yang

Abstract:

This tutorial is devoted to pseudo-spectral method (PSM) by reorganizing the course material from Prof. Heiner Igel and a paper by J.M. Carcione, to illustrate how to implement viscoacoustic wave simulation based on fractional Laplacian operator.
