Data and software for "A quasi-P- and quasi-SV-wave Decoupled Acoustic-Elastic Coupled Equation System for VTI Media"

This repository contains the data and source code supporting the manuscript “Acoustic-elastic coupled equations for qP/qS-wave decoupling in anisotropic media.” The archive contains three main directories: data, plot_figure_program, src and output. The data directory contains the figure data used in the manuscript. For clarity, it is further divided into five subdirectories: snapshot_homogeneous_elliptical, snapshot_homogeneous_weak, snapshot_homogeneous_strong, snapshot_layer, and snapshot_complex. These subdirectories contain wavefield snapshots for a homogeneous elliptical anisotropic medium, a homogeneous weak anisotropic medium, a homogeneous strong anisotropic medium, a layered anisotropic medium, and a complex anisotropic medium, respectively. The plot_figure_program directory contains the plotting scripts and instructions used to reproduce the main numerical examples and figures presented in the manuscript. The src directory contains the source code for acoustic-elastic coupled wavefield modeling and qP/qS wave-mode decoupling. The output directory is used to store the output files generated by running the source code in the src directory, including numerical simulation results, wavefield snapshots, and wavefield decomposition results. The contents of this directory can be regenerated by users by following the provided running instructions. If the directory is empty in the archived package, users should create it before running the source code. These materials are provided to support the development, validation, and application of the proposed acoustic-elastic coupled equations and qP/qS wave-mode decoupling method in anisotropic media. The included files can be used to reproduce the model setup, numerical experiments, representative wavefield snapshots, and figures reported in the study.
