Abstract

The one-dimensional electromagnetic problem of a current sheet source in a dispersive DNG medium was considered. A lossy Drude model of the DNG medium was used. The solution was generated numerically with the FDTD method. The analogous problem in a nondispersive DNG medium was also considered. It was shown that the solution to this problem is not causal in agreement with similar observations given in previous studies. Approximate solutions that combined causal envelopes and the NIR properties of the nondispersive DNG medium were constructed and shown to compare well to the FDTD results for the dispersive DNG medium.
