Fresnel Integral Computation Techniques
Alexandru Ionut, James C. Hateley
This work is an extension of previous work by Alazah et al. [M. Alazah, S. N. Chandler-Wilde, and S. La Porte, Numerische Mathematik, 128(4):635-661, 2014]. We split the computatio…
Convergence of the Frozen Gaussian Approximation for High Frequency Elastic Waves
James Hateley, Xu Yang
The frozen Gaussian approximation (FGA) is an effective tool for modeling high frequency wave propagation. In previous works, the convergence of the FGA has established for strict…
Frozen Gaussian Approximation for 3-D Elastic Wave Equation and Seismic Tomography
James C. Hateley, Lihui Chai, Ping Tong +1
The purpose of this work is to generalize the frozen Gaussian approximation (FGA) theory to solve the 3-D elastic wave equation and use it as the forward modeling tool for seismic…
Deep Learning Seismic Substructure Detection using the Frozen Gaussian Approximation
James C. Hateley, Jay Roberts, Kyle Mylonakis +1
We propose a deep learning algorithm for seismic interface and pocket detection with neural networks trained by synthetic high-frequency displacement data efficiently generated by…
