Two-Dimensional Full-Waveform Joint Inversion of Surface Waves Using Phases and Z/H Ratios

open access: yesApplied Sciences, 2021
Surface-wave dispersion and the Z/H ratio are important parameters used to resolve the Earth’s structure, especially for S-wave velocity. Several previous studies have explored using joint inversion of these two datasets.

Unrolled Convolutional Neural Network for Full-Wave Inverse Scattering

open access: yesIEEE Transactions on Antennas and Propagation, 2023
An unrolled deep learning scheme for solving full- wave nonlinear inverse scattering problems (ISPs) is proposed. Inspired by the so-called unrolled method, an iterative neural network structure combining the contrast source inversion (CSI) method and residual network (ResNet) is designed.
