| Abstract: |
| In this paper, we are concerned about the stability analysis for a Perfectly Matched Layer (PML) recently developed by B′ecache 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. |
