Tube waves, seismic waves and effective sources [PDF]
Wave Motion, 1993 The radiation of waves from a monopole source in a fluid-filled borehole into an elastic medium is considered. 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.

Seismic barriers: theory and numerical simulations [PDF]
E3S Web of Conferences, 2019 The basic idea of a seismic barrier is to protect an area occupied by a building or a group of buildings from seismic waves. Depending on the nature of seismic waves that are the most probable in a specific region, different kinds of seismic barriers are

Geophysical Journal International, 1996 SUMMARY The concept of a seismic image wave is introduced and explained with the aid of some examples. Seismic reflector images in various domains (e.g. depth-migrated reflections in the depth domain or common-offset reflections in the time domain) behave like snapshots of elementary body waves.

Transformation seismology: composite soil lenses for steering surface elastic Rayleigh waves. [PDF]
, 2016 Metamaterials are artificially structured media that exibit properties beyond those usually encountered in nature. Typically they are developed for electromagnetic waves at millimetric down to nanometric scales, or for acoustics, at centimeter scales. By

About applying Rayleigh formula based on the Kirchhoff integral equations for the seismic exploration problems [PDF]
Компьютерные исследования и моделирование, 2017 In this paper we present Rayleigh formulas obtained from Kirchhoff integral formulas, which can later be used to obtain migration images. The relevance of the studies conducted in the work is due to the widespread use of migration in the interests of ...

The direct boundary element method: 2D site effects assessment on laterally varying layered media (methodology) [PDF]
, 2004 The Direct Boundary Element Method (DBEM) is presented to solve the elastodynamic field equations in 2D, and a complete comprehensive implementation is given. The DBEM is a useful approach to obtain reliable numerical estimates of site effects on seismic
