Abstract
Metamaterial of twisted metallic foil pairs is proposed. Resonances are illustrated in both transmission and reflection. Negative refraction index can be realized by chiral configuration of this metamaterial. Parallel and antiparallel surface currents form magnetic and electric dipoles. The cross coupling between electric and magnetic field presents chirality. © 2010 Wiley Periodicals, Inc.
