The perfectly matched layer (PML) boundary condition for the beam propagation method
IEEE Photonics Technology Letters, 1996The perfectly matched layer (PML) boundary condition for the Helmoltz equation is developed and applied to the finite-difference beam propagation method. Its effectiveness is verified by way of examples.

Implementation of Perfectly Matched Layer (PML) for the WCS-FDTD Method Using DSP Techniques
IEEE Antennas and Wireless Propagation Letters, 2014An efficient implementation of perfectly matched layer (PML), based on the stretched coordinate PML (SC-PML) and digital signal processing (DSP) techniques, is proposed to truncate the weakly conditional stable finite-difference time-domain (WCS-FDTD) lattices.

A finite‐element‐method frequency‐domain application of the perfectly matched layer (PML) concept
Microwave and Optical Technology Letters, 1995AbstractThe perfectly matched layer (PML) concept, introduced by Berenger with the aim of synthesizing an absorbing boundary condition (ABC) for the finite‐difference‐time‐domain (FDTD) method, is modified and extended to the frequency domain for FEM applications.

A new modified perfectly matched layer( PML) without split-field
2008 International Conference on Microwave and Millimeter Wave Technology, 2008The perfectly matched layer (PML) is a technique of free-space simulation developed for solving open region electromagnetic problems with numerical simulation methods. However, the original PML will consume a considerable amount computer resources and computing time due to the split-fields.

A modified perfectly matched layer (PML) for waveguide problems
Microwave and Optical Technology Letters, 1998An efficient perfectly matched layer (PML) is proposed for waveguides. In this letter, the PML region is simulated in one dimension, which improves the computational efficiency. A WG-90 rectangular waveguide with a thick inductive iris is analyzed by the finite-difference time-domain (FDTD) method with Berenger' PML and the proposed PML.

The perfectly matched layer (PML) concept has been introduced recently by Berenger (1994) with the objective of developing an absorbing boundary condition for the finite difference time domain (FDTD) method. In its original formulation, the PML approach is based on the splitting of the field components into two sub-components which are weighted with ...

The absorbing boundary condition (ABC) and the perfectly matched layer (PML) are employed to suppress the numerical reflections in wave propagation methods. The PML has earlier been shown to fail at the grazing angle propagation of beam. The ABC is preferred over the PML where refractive index is not an analytic function.

Since its introduction in 1994 by Berenger for Maxwell's equations, the perfectly matched layer (PML) technique has become classical in numerical simulations of wave propagation. In this study, we extend the convolution-perfectly matched layer (C-PML) method developed for first-order and second-order systems describing elastic waves in anisotropic ...
