Miniaturized Mirror C-Shaped Negative Index Engineered Material for L-, S-, and C-band Applications

Abstract

A new mirror C-shaped with square split resonators engineered material unit cell structure proposed for L-, S-, and C-band applications. The design structure has shown the negative refractive index (NRI) property along with the x-axis wave propagation. The finite integration technique (FIT) based Computer Simulation Technology (CST) microwave studio software and finite element method based High Frequency Structure Simulator (HFSS) software are adopted to investigate the proposed design structure. The parametric studies have been done based on the substrate's thickness. The engineered material unit cell structure acquired higher effective medium ratio (21.71) and exhibited the NRI properties at 1.47 GHz frequency. The higher wideband (5.63 GHz) also attained by the proposed design structure. The results of the proposed engineered material demonstrated L-, S-, and C-bands response over the frequency ranges from 1 to 10 GHz. Hence, the proposed structure enables numerous application areas of L-, S-, and C-bands.
