A Tutorial on Monochromatic Waves
, by Raul Estevez
In the present study we shall review the application of a technique
of numerical extrapolation of monochromatic waves, to some theoretical
models. The already knwon technique, described in Claerbout (1970a), (1970b)
refers to the computation of vertical or quasi-vertical downgoing waves in
a lightly inhomogenous medium by means of finite difference approximations
to the scalar acoustic wave equation. In our case, the technique was
applied to study the downward continuation of a plane wave through a
quasi-inhomogeneous medium with different two dimensional geometrical
bodies of slightly different velocity embedded within it.
