WebDec 31, 2002 · Abstract. Ray theory is a high-frequency approximation on which most of the seismic interpretation relies. This theory is used to determine crustal structure and it largely dominates ... Webequations for the amplitudes of the ray-theory elastodynamic Green function is lat-erally varying layered structures are derived. Great attention is also devoted to the ray-series solutions, both in the frequency and the time domain. The seismological applications of higher-order terms of the ray series are discussed. See Chapter 5.

Store. SEG Online Store. The concept of a ray is extremely useful. Rays are curves drawn in space, and they correspond to the directions of flow of propagated energy. In other word, rays are flow lines. Being flow lines, rays cannot cross each other. As such, the ray is a mathematical device rather than a physical entity. dictionary below
