    • Optimal Absorbing Boundary Conditions For Finite Difference Modeling Of Acoustic And Elastic Wave Propagation 

      Peng, Chengbin; Toksoz, M. N. (Massachusetts Institute of Technology. Earth Resources Laboratory, 1993)
      An optimal absorbing boundary condition is designed to model acoustic and elastic wave propagation in 2D and 3D media using the finite difference method. In our method, extrapolation on the artificial boundaries of a ...

    • Tube Waves, Seismic Waves And Effective Sources 

      Burridge, Robert; Kostek, Sergio; Kurkjian, Andrew L. (Massachusetts Institute of Technology. Earth Resources Laboratory, 1993)
      A simple asymptotic analysis, based on the smallness of the ratio of the borehole radius to the wavelength, reveals the interaction between tube waves and seismic waves. The pressure field in a tube wave acts as a secondary ...

    • Dynamic And Static Green's Functions In Transversely Isotropic Elastic Media 

      Dong, Wenjie; Schmitt, Denis P. (Massachusetts Institute of Technology. Earth Resources Laboratory, 1993)
      Concise and numerically feasible dynamic and static Green's functions are obtained in dyadic form by solving the wave equation and the equilibrium equation with general source distribution in transversely isotropic (TI) ...
