In this paper, we design the structures for microwave containing 'left-handed' metamaterials – artificial composites with simultaneously negative effective permittivity and permeability which achieve negative values of refractive index. Attention has been given to the fundamentals of negative index materials, the main design strategies and proposed applications which include Absorber, subwavelength resonant cavities, sub-diffraction limited nearfield lenses (superlenses) and phase compensators, which shows a single negative permeability and Refractive Index characteristics at 1-15 GHz frequency ranges. The Absorber is made of Fourth layered Swastika-shaped conductors as a patch and the dielectric substrate, which shows the characteristic of single negative properties of light at different frequency ranges. The permeability has -91dB negative properties in the 1.06 to 1.21 GHz frequency and -16.5 dB in 9.16 to 9.23 GHz frequency ranges. The permittivity of fourth-layered rectangular SRR Swastika-shaped metamaterial has -212 dB negative properties of metamaterial in 1.97 to 2 GHz, -196 dB in 2.5 to 2.8 GHz, -16 dB in 4.6 to 5.29 GHz and -90 dB in 10.23 to 10.25 GHz frequency ranges, which shows the characteristics of Absorber, subwavelength resonant cavities, sub-diffraction limited near-field lenses (superlenses) and phase compensators of the electromagnetic waves of proposed structure. Index Terms — Metamaterial, FSS, Swastika-shaped metamaterial, CST and Rectangular SRR.
