Abstract

A double-arrow-shaped negative refractive index (NRI) metamaterial is presented that magnetic inclusion was etched by copper over the epoxy resin composite with woven glass fabric, and its performance was investigated for two incidences (xand z-axis) of the metamaterial. The numerical and experimental transmittance (S21) are well compiled at 6.52 GHz, whereas the metamaterial shows double negative characteristics at 7.51 GHz. Further, the NRI metamaterial refractive index curve shows the negative region peaks from 5.01 GHz to 6.06 GHz (nearly 1 GHz bandwidth) and 7.37 GHz to 10 GHz (more than 2 GHz bandwidth) in the microwave regions for the z-axis wave propagation. A circuit model and necessary experimental results were provided to demonstrate the resonant behavior. Besides, the metamaterial displays the NRI property in the region of S-, C- and X-bands for the x-axis transmission with better effective medium properties..
