Nearly perfectly matched layer method for seismic wave propagation in poroelastic media
The nearly perfectly matched layer (NPML) method has been successfully applied to electromagnetic and elastodynamic wave equations including elastic isotropic and anisotropic media types to absorb spurious arrivals reflected from introduced boundaries in a number of numerical solution methods. It has been shown to be extremely satisfactory for this purpose. In this paper, a first-order velocity...
متن کاملThe application of the perfectly matched layer in numerical modeling of wave propagation in poroelastic media
The perfectly matched layer (PML) was first introduced by Berenger as a material absorbing boundary condition (ABC) for electromagnetic waves. In this paper, a method is developed to extend the perfectly matched layer to simulating seismic wave propagation in poroelastic media. This nonphysical material is used at the computational edge of a finite-difference algorithm as an ABC to truncate unb...

متن کاملApplication of the perfectly matched layer (PML) absorbing boundary condition to elastic wave propagation
A method is presented for application of the perfectly matched layer !PML" absorbing boundary condition !ABC" to the P-SV velocity–stress finite-difference method. The PML consists of a nonphysical material, containing both passive loss and dependent sources, that provides ‘‘active’’ absorption of fields. It has been used in electromagnetic applications where it has provided excellent results f...
متن کاملPerfectly Matched Layers equations for 3D acoustic wave propagation in heterogeneous media
This work is dedicated to the analysis of Berenger PML method applied to the 3D linearized Euler equations without advection terms, with variable wave velocity and acoustic impedance. It is an extension of a previous work presented in a 2D context [8]. The 3D linearized Euler equations are used to simulate propagation of acoustic waves beneath the subsurface. We propose an analysis of these equ...
