Abstract
Metamaterials are the artificial material having negative properties of permittivity and permeability. Such types of artificial materials exhibit many unnatural properties that do not exist in nature. These unnatural properties can be utilized in many smart devices for beamforming, suppressing reactive fields, SAR and size minimization. The study emphasis on structural modeling of double negative metamaterials having frequency reconfigurable properties. The design is evaluated for negative characteristics of refractive index, permittivity and permeability using novel flower leaf resonator. The proposed unit cell consists of a compact size square shaped FR4 dielectric substrate with dual side printing of metallic flower. The design is exhibiting reconfigurable properties with the variation in the number of leaves and is capable of shifting its transition to the lower end with the increasing number of leaves. The novel structure is compact enough (5 × 5 mm2) to be fit in any metamaterial application. The design is simulated and analyzed using CST microwave studio.
