AB - <p style="text-align: justify;">In this paper, we are concerned about the stability analysis for a
Perfectly Matched Layer (PML) recently developed by Bécache et al. [5] for
simulating wave propagation in the Drude metamaterial. This PML is proved to
be stable originally in [6] through a modal analysis. Here we establish its stability
by the energy method. A FDTD scheme is developed and analyzed. Numerical
simulations illustrate the stability of the PML model and its effectiveness in
absorbing outgoing waves in the Drude medium.</p>
