Abstract

This paper proposes a new planner metamaterial consisting of crescent shaped split ring resonator unit cells. The cell is composed of a crescent shaped strip over one face of a dielectric substrate, and an oblong over the second face. The cell is very thin and easy to fabricate. The transmission characteristics of the structure were obtained using High Frequency Structure Simulator (HFSS) commercial software by ANSOFT. Then the effective material properties were retrieved. All the transmission characteristics and material properties were plotted to show the material behavior with frequency. The new metamaterial provides a double negative refractive index over a specific frequency band.
