Abstract

In this paper, a 2-D composite medium that exhibits simultaneously negative values of permittivity and permeability over a broad frequency range is proposed. The broadband negative permeability is achieved by interconnecting split-ring resonators (capacitively loaded metallic rings) while the broadband negative permittivity is achieved in a standard manner using inductive wires. The composite medium exhibits a negative refractive index (NRI) for S-polarized (TE) waves. Its dispersion characteristics, obtained through fullwave analysis, show that the refractive index of the medium remains negative over a 60% bandwidth (from 1.64 GHz to 3.05 GHz)
