Wide-angle one-way wave equations

The Journal of the Acoustical Society of America, 1988
A one-way wave equation, also known as a paraxial or parabolic wave equation, is a differential equation that permits wave propagation in certain directions only. Such equations are used regularly in underwater acoustics, in geophysics, and as energy-absorbing numerical boundary conditions.

One-way wave equations for seismoacoustic propagation in elastic waveguides

The Journal of the Acoustical Society of America, 1990
One-way or parabolic wave equations for time-harmonic propagation in two-dimensional elastic waveguides are considered. It is shown that the direct application of a rational linear approximation with real coefficients to the elastic wave propagation case results in exponential growth in the numerical solutions.

The Theory of True Amplitude One‐Way Wave Equation Migrations

Chinese Journal of Geophysics, 2006
AbstractIn this technical report, we review the recent development of true amplitude one‐way wave equation migration and summarize the migrated amplitude performance from different one‐way wave equations. To produce correct amplitude from postack phase‐shift migration, we have to apply accurate geometrical spreading compensation in preprocessing ...

Optimization of one-way wave equations

Geophysics, 1985
Abstract The theory of wave extrapolation is based on the square-root equation or one-way equation. The full wave equation represents waves which propagate in both directions. On the contrary, the square-root equation represents waves propagating in one direction only.
