Backward waves in a grounded bilayer slab containing double-negative (DNG) and double-positive (DPS) metamaterials
E. Cojocaru
Simple dispersion relations for the guided modes in a grounded DNG/DPS bilayer slab are given in terms of normalized parameters. Relations corresponding to the grounded single-laye…

Animations obtained by the finite-difference time-domain method showing the backward wave propagation in double-negative single-layer waveguides
E. Cojocaru
The materials having negative permittivity and negative permeability, which are labeled as double-negative (DNG) materials, have attracted much attention because of their unusual p…
