Abstract

Numerical studies of vane-type, double negative, fishnet metamaterial structure is presented. The constitutive electromagnetic parameters of the double-sided vane-type structure are extracted through both Kramers-Kronig (K-K) method and the parameter fitting of dispersive models (PFDM) method. The designed metamaterial structure is shown to exhibit negative refractive index,approximately, from 15-16 GHz with the lowest refractive index of -10.53 at 15.4 GHz. The double negative behavior in this frequency range is further confirmed through the simulation of the equivalent bulk medium of the designed metamaterial structure in a wedge-shaped structure. The negative refraction exhibited by the equivalent bulk medium in the wedge-shaped structure is also shown and discussed.
