A New Double Negative Metamaterial for C-Band Microwave Applications

Abstract:

Metamaterials are artificial materials that show extra ordinary electromagnetic properties which are not available in nature. It has opened a new era in the field of material science. It can be defined as an exotic electromagnetic structure that may show both negative permittivity and negative permeability simultaneously within a frequency range. Metamaterials with simultaneous negative permeability and permittivity are called Double Negative Metamaterials (DNG). In this paper, a new metamaterial unit cell structure has been proposed that exhibits resonance within frequency of C-band and shows a negative permeability and permittivity at that resonant frequency. In the proposed structure, two separate split ring resonators and a metallic bar has been used. A commercially available simulation software CST Microwave Studio has been used to get the reflection and transmission parameters for the unit cell.
