Abstract
The paper reveals a near zero refractive index (NZRI) property based metamaterial unit cell for electromagnetic cloaking operation. The metamaterial unit cell displays resonance in the frequency of 8.29 GHz and exhibits near zero refractive index property there. The metamaterial was then utilized in designing a single layer rectangular cloaking device. The rectangular cloaking device hides a cylindrical metal object in the C-band region where almost zero scattering cross section is achieved for the object. The metamaterial also exhibits NZRI property there. The commercially available CST Microwave Studio simulation software, was utilized to obtain all the reflection and transmission parameters of the unit cell and the cloak. The experimental results were presented as well for both of the metamaterial and the cloak. It was also revealed that the cloak was object size independent in the certain region of C-band. This is a promising design in the electromagnetic paradigm for the rectangular and C-band cloaking operation.
