Curved perfectly matched layer in frequency domain

International Journal of Numerical Modelling: Electronic Networks, Devices and Fields, 2000
Summary: In this paper, the basic principle that a Perfectly Matched Layer (PML) is viewed as a complex change of variables is applied to curvilinear co-ordinates. We give a general model based on tensor analysis, which is able to design any shape of PML. Some applications of the model and results of the numerical analysis are presented.

Conformal perfectly matched layer

2013
An analytic derivation of the true three-dimensional conformal perfectly matched layer (PML) on a general orthogonal curvilinear coordinate system is presented. The conformal PML can be expressed in terms of an anisotropic constitutive tensor depending on the local principal radii of the curvatures of the termination surfaces.

The Perfectly Matched Layer for Computational Acoustics

1995
Recently, Berenger [1] formulated, for the finite difference — time domain solution of Maxwell’s equations in two dimensions, a new absorbing boundary, which he called a perfectly matched layer (PML). His demonstration that the PML possesses extraordinary energy-absorbing properties was verified by Katz, et al. [2], who also extended the formulation to

Stabilized Perfectly Matched Layer for Advective Acoustics

2003
In this paper we present a stabilized Perfectly Matched Layer (PML) for the subsonic aeroacoustics equations. The PML method was introduced by Berenger [2] to compute the solution of Maxwell’s equations in unbounded domain. This method was adapted by Hu [4] to the aeroacoustics equations.

Discretization of Continuous Spectra Based on Perfectly Matched Layers

SIAM Journal on Applied Mathematics, 2004
The author gives a detailed analysis of the fact that the condition of perfectly matched layer (PML) changes the character of an open waveguide, whose mathematical description has its spectrum with continuous part into the character of the closed waveguide (bounded in the transversal plane) whose mathematical description has a discrete spectrum.
