Abstract :
In this paper, we discussed mode spectrum of a grounded dielectric slab with DNG medium and its pole loci as the thickness or loss changes. They are more complicated than those of conventional DPS medium, and these complexities suggest a different Sommerfeld integral path for DNG medium.
