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:
