Stability analysis of the perfectly matched layer for the elastic wave equation in layered media

Published 2022-10-01Version 1

In this paper, we present the stability analysis of the perfectly matched layer (PML) in two-space dimensional layered elastic media. Using normal mode analysis we prove that all interface wave modes present at a planar interface of bi-material elastic solids are dissipated by the PML. Numerical experiments in two-layer and multi-layer elastic solids corroborate the theoretical analysis.
