A numerical tour of wave propagation |

The innovative work was done by John Claerbout, and is well-known as wave equation to separate the up-going and down-going waves (Claerbout, 1971,1986).

Eliminating the source term, the Fourier transform of the scalar wave equation (Eq. (5)) can be specified as:

(17) |

The down-going wave equation in Fourier domain is

(18) |

Using the different order Pade expansions, we have:

(19) |

The corresponding time domain equations are:
