    Single-frequency approximation of the coupling ray theory

  • Original language description

    The coupling-ray-theory Green tensor is frequency dependent, and is usually calculated for many frequencies. This frequency dependence represents no problem for calculating the Green tensor, but may represent a great problem when storing the Green tensorat the nodes of dense grids, typical for applications such as seismic migrations. This paper is devoted to the approximation of the coupling-ray-theory Green tensor, which eliminates this frequency dependence. In the vicinity of a given prevailing frequency, we approximate the frequency-domain coupling-ray-theory Green tensor by two Green tensors corresponding to two S waves described by their travel times and amplitudes. We refer to these travel times and amplitudes as the coupling-ray-theory travel times and the coupling-ray-theory amplitudes. This "single-frequency approximation" of the coupling ray theory allows us to process the coupling-ray-theory wavefield in the same way as the anisotropic-ray-theory wavefield. This simplificat
