Wave extrapolation is the process of extending a known wave pattern beyond its observed domain, using mathematical or computational methods to predict how the wave continues. This technique is especially useful in fields like seismology, acoustics, and signal processing, where it’s often necessary to infer wave behavior in regions that are difficult or impossible to measure directly. Extrapolation can be performed in the time domain, where future wave motion is estimated, or in the spatial domai
