For an ingoing plane wave ei→k ⋅ →r, the wavefunction far away from the scattering region must have the form ψ→k(→r) = ei→k ⋅ →r + f(θ, φ)ei k r r. where θ, φ are measured with respect to the ingoing direction. Note that the scattering amplitude f(θ ...

WebLinear elasticity as a general three-dimensional theory began to be developed in the early 1820s based on Cauchy’s work. Simultaneously, Navier had developed an elasticity theory based on a simple corpuscular, or particle, model of matter in which particles interacted with their neighbours by a central force attraction between particle pairs. As was gradually … WebIt assumes that the vertical geophone component records mostly pressure waves. If this assumption is not satisfied, non-pressure wave energy (such as shear waves) will be introduced as pressure waves into the receiver wavefield, which may generate artifacts in the migration image. I formulate an elastic Born modeling and migration method…
