The Journal of the Acoustical Society of America, 1996 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.

Enhanced PML Based on the Long Short Term Memory Network for the FDTD Method
IEEE Access, 2020 This paper proposes a new absorbing boundary condition (ABC) computation approach based on the deep learning technique. Benefited from the sequence dependence feature, the Long Short-Term Memory (LSTM) network is employed to replace the conventional ...

Notes on Perfectly Matched Layers (PMLs)
CoRR, 2021 This note is intended as a brief introduction to the theory and practice of perfectly matched layer (PML) absorbing boundaries for wave equations, originally developed for MIT courses 18.369 and 18.336. It focuses on the complex stretched-coordinate viewpoint, and also discusses the limitations of PML.

Study on Influence of Thickness and Electromagnetic Parameter of Perfectly Matched Layer (PML) [PDF]
The Open Electrical & Electronic Engineering Journal, 2014 Perfectly matched layer (PML) absorbing boundary condition (ABC) is an important technique in finitedifference time-domain (FDTD) when simulating infinite area's electromagnetic behaviour in finite area. A big enough computational area was designed in which there is no influence of reflective wave.

Review and Recent Developments on the Perfectly Matched Layer (PML) Method for the Numerical Modeling and Simulation of Elastic Wave Propagation in Unbounded Domains [PDF]
Archives of Computational Methods in Engineering, 2021 This review article revisits and outlines the perfectly matched layer (PML) method and its various formulations developed over the past 25 years for the numerical modeling and simulation of wave propagation in unbounded media. Based on the concept of complex coordinate stretching, an efficient mixed displacement-strain unsplit-field PML formulation for
