Abstract

The increasing interest in negative‐index metamaterials requires a formulation capable of a full analysis of wave propagation in such materials. Since two‐dimensional (2D) problems have been largely explored in the literature, the natural step is a three‐dimensional (3D) formulation of a metamaterial. In this work, we present a simulation of a left‐handed metamaterial using the finite‐difference time‐domain (FDTD) method in conjunction with perfectly matched layers (PMLs). First, we develop a PML to work with a Drude medium model. Then we apply our formulation to a 3D domain and compare our results with 2D problems. Finally, we simulate a dipole on the top of a metamaterial slab, presenting the field distribution in three different directions. © 2004 Wiley Periodicals, Inc.
