Review of the methodology for computation of transmission and reflection coefficients for the surface waves propagated through a vertical contact

In this paper, a review of the methodology for the computation of transmission and reflection coefficients for the surface waves, propagated through a vertical contact, will be presented and discussed. The surface-wave transmission and reflection coefficients will be obtained using a simple method. This method will be very briefly described and compared with a more sophisticate method, obtaining the Rayleighwave transmission coefficients for the ocean-continent boundary, existing between the Atlantic Ocean and the Iberian Peninsula. This simple method will be shown as ef f icient as other more sophisticate methods, computing a theoretical curve (the theoretical Rayleigh-wave transmission coefficients) as close as possible to the observed data (the observed Rayleigh-wave transmission coefficients, previously measured for the boundary considered). Thus, the validity and reliability of this simple method, proposed in this paper, will be proven. This simple method should be a useful tool, to study the vertical contacts between two structures (as faults or continent-ocean boundaries), for many areas of the Earth, if the elastic properties of the media in both sides of the contact (and the density distribution with depth) are well known in advance.
