Pulse Propagation in Random Media

摘要

The document is divided into 3 parts: (1) Multiple scattering of electromagneticwaves in randomly layered dissipative media. The magnetotelluric (MT) problem considered has lent itself to modeling within the weak noise or Gauss Markov regime. In addition to considering propagation per se, the issue of the detection of anomalous layers has been addressed. Details are presented in the enclosed preprint, Random Scattering in Magnetotellurics, by Benjamin White, Werner Kohler, and Leonard Srnka, which has been submitted for publication to Geophysics. (2) Extension of the ideas mentioned above to the case of an undulating (locally layered) medium. The theory developed for layered media is shown to be robust. (3) Incorporation of the above analysis into an inversion strategy.
