Fishnet Structure: The Occurrence of Left-Handed Behavior Over a Wide Range of Geometrical Parameters Irini Tsiapa, Nikos Katsarakis*, Maria Kafesaki, George Kenanakis, Costas M. Soukoulis, Eleftherios N. Economou Institute of Electronic Structure and Laser (IESL), Foundation for Research & Technology-Hellas (FORTH), P.O. Box 1527, Vassilika Vouton, 711 10 Heraklion, Crete, Greece *katsan@iesl.forth.gr Left-handed metamaterials (LHMs), i.e. artificial materials that exhibit both negative effective electrical permittivity, ε and magnetic permeability, µ, over a common frequency band, have received recently a lot of attention due to their interesting electromagnetic (EM) properties that create new perspectives for the manipulation of electromagnetic waves (negative refraction, evanescent wave amplification, perfect lensing etc). Here, we have carried out a systematic study of the so-called fishnet design in the microwave frequency region, and have demonstrated its advanced performance, namely its ability to produce left-handed behavior over a wide range of structure parameters. The role of the various geometrical parameters on the resonance frequency and strength has been investigated by means of free-space microwave measurements and simulations using the Finite Integration Technique, employed through the MicroWave Studio commercial software.
