2004 journal article

Modified integration rules for reducing dispersion error in finite element methods

*COMPUTER METHODS IN APPLIED MECHANICS AND ENGINEERING*, *193*(3-5), 275–287.

author keywords: wave propagation; numerical dispersion; numerical integration; Helmholtz equation

TL;DR:
The method involves a simple shift of the integration points to locations away from conventional Gauss or Gauss–Lobatto integration points, which results in fourth-order accuracy with respect to dispersion error (error in wavelength), as opposed to the second- order accuracy resulting from conventional integration.

2003 journal article

On optimal finite-difference approximation of PML

*SIAM JOURNAL ON NUMERICAL ANALYSIS*, *41*(1), 287–305.

author keywords: absorbing boundary conditions; exponential convergence; finite differences; hyperbolic problems; perfectly matched layers; wave propagation; optimal rational approximations

TL;DR:
It is found that the minimal error can be achieved using pure imaginary coordinate stretching, and the PML discretization is algebraically equivalent to the rational approximation of the square root on [0,1] conventionally used for approximate absorbing boundary conditions.
