    • Electroseismic Waves From Point Sources In Layered Media 

      Haartsen, Matthijs W.; Toksoz, M. N. (Massachusetts Institute of Technology. Earth Resources Laboratory, 1995)
      The macroscopic governing equations controlling the coupled electromagnetics and acoustics of porous media are numerically solved for the case of a layered poro-elastic medium.It is shown that these coupled equations ...

    • Scattering Of Acoustic And Elastic Waves Using A Hybrid Multiple Multipole Expansions-Finite Element Technique 

      Imhof, Matthias G. (Massachusetts Institute of Technology. Earth Resources Laboratory, 1995)
      In this paper, two different methods to solve scattering problems in acoustic or elastic media are coupled to enhance their usefulness. The multiple multipole (MMP) expansions are used to solve for the scattered fields ...

    • 3-D Traveltime Modeling With Application To Seismic Imaging And Tomography 

      Matarese, Joseph R. (Massachusetts Institute of Technology. Earth Resources Laboratory, 1995)
      Fast algorithms exist for performing traveltime modeling, even in three dimensions. These algorithms have the nice property that the computational time and memory requirements scale linearly with the number of grid points ...
