2011 journal article

Absorbing boundary conditions for time harmonic wave propagation in discretized domains

COMPUTER METHODS IN APPLIED MECHANICS AND ENGINEERING, 200(33-36), 2483–2497.

By: S. Thirunavukkarasu & M. Guddati*

author keywords: Artificial boundary conditions; Perfectly matched layers; Discrete absorbing boundary conditions; Wave propagation; Helmholtz equation
TL;DR: It is shown that the discrete system (mesh) can be stretched in a non-trivial way to preserve the discrete impedance at the interface, resulting in a PML-type ABC for discrete media. (via Semantic Scholar)

Phonon absorbing boundary conditions for molecular dynamics

JOURNAL OF COMPUTATIONAL PHYSICS, 228(21), 8112–8134.

By: M. Guddati n & S. Thirunavukkarasu n

author keywords: Atomistic-to-continuum coupling; Artificial boundary conditions; Absorbing boundary conditions; Perfectly matched layers
TL;DR: It is concluded that MD-PMDL could provide a more effective alternative to existing MD-ABCs, which are extensions of perfectly matched discrete layers that target the absorption of phonons, the high frequency waves, whose propagation properties are completely different from continuous waves.
