A geometrical description of the
domain isotropic wavefield can be achieved by looking at its eikonal. A dispersion relation associated with the
domain wave equation 15 is obtained by taking Fourier transform of this equation in space and time, specifically, do the substitution
and
, the result is
We then relate slowness vector
with wavenumber vector
by
, thus the
domain isotropic eikonal equation is
