Equivalent anisotropic first-order pseudo-acoustic wave equations modeling and its efficiency analysis
摘要
Abstract
In order to overcome the limitations of anisotropic elastic wave equa-tions modeling,this paper studied anisotropic pseudo-acoustic wave modeling by using staggered-grid finite-difference method.Starting from two different ideas, i.e .,Hooke’s law and qP-qSV dispersion relation for VTI media,two first-order pseudo-acoustic wave equations in two forms for VTI media are given.关键词
