Optimal wave focusing in elastic media

چکیده
Time-reversal (TR) methods provide a simple and robust solution to source imaging problems. However, for recovering a well resolved image of the source, TR requires a balanced illumination of the target from all angles. When acquisition is incomplete and a balanced illumination is not possible, the TR solution may not be adequate. In a previous paper, by formulating source imaging as an optimization problem, we presented a method named Backus-Gilbert focusing (BG) to enhance the performance of TR in acoustic media despite incomplete acquisition. Here, we generalize the theory of BackusGilbert focusing for application in elastic media.

متن کاملExistence of extraordinary zero-curvature slowness curve in anisotropic elastic media.
Acoustic wave propagation in elastic media is characterized by the slowness surface. The slowness surface consists of three sheets associated with three modes of wave propagation and the two outer sheets can have zero-curvature locally. It is shown that the outmost sheet can admit extraordinary zero-curvature and the slowness curve can appear as a straight line locally. Using the perturbation m...

متن کاملFocusing of elastic waves for microseismic imaging
Microseismic events generate compressive waves and shear waves which can be recorded at receivers. We present a theory that shows how elastic P and S waves separately backpropagate to the original source location. These refocused P and S wavefields are free of singularities. We also demonstrate a technique that enhances the ability to image the spatial focus for each wave type using elastic wav...
