Title |
High-frequency imaging of the earth |
Abstract |
Intensive research is currently taking place in the geophysics community to model wave propagation in anisotropic models of the earth’s subsurface. We investigate the associated inverse problem of estimating elastic and electrical properties of the earth from measurements of scattered elastic and electro-magnetic waves. We adopt the high-frequency linearized inversion approach to see what model parameters of the earth can be recovered and how to recover them. The results of this research are useful in determining locations of oil and mineral deposits. Other applications include ultra-sound (medical) imaging, mine detection, location of cracks in materials, etc. |
