36th International Conference on Infrared, Millimeter, and Terahertz Waves (IRMMW-THz), Texas, Amerika Birleşik Devletleri, 2 - 07 Ekim 2011, (Tam Metin Bildiri)
A dual-band polarization-independent fishnet metamaterial for THz frequencies is proposed and investigated. Dual-band modes have two resonances in which the first one is fixed as a left-handed mode and the second one can be arranged as a left-handed or single-negative mode. We select the character of the second resonance by the choice of substrate properties.
