2011 article
Absorbing boundary conditions for time harmonic wave propagation in discretized domains
Thirunavukkarasu, S., & Guddati, M. N. (2011, May 18). Computer Methods in Applied Mechanics and Engineering, Vol. 200, pp. 2483–2497.
author keywords: Artificial boundary conditions; Perfectly matched layers; Discrete absorbing boundary conditions; Wave propagation; Helmholtz equation
topics (OpenAlex): Electromagnetic Simulation and Numerical Methods; Electromagnetic Scattering and Analysis; Lightning and Electromagnetic Phenomena
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.

2009 article
Phonon absorbing boundary conditions for molecular dynamics
Guddati, M. N., & Thirunavukkarasu, S. (2009, August 5). Journal of Computational Physics, Vol. 228, pp. 8112–8134.
author keywords: Atomistic-to-continuum coupling; Artificial boundary conditions; Absorbing boundary conditions; Perfectly matched layers
topics (OpenAlex): Electromagnetic Simulation and Numerical Methods; Ultrasonics and Acoustic Wave Propagation; Acoustic Wave Phenomena Research
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.
