Abstract

The Metamaterials are artificial composite structures that exhibit a homogeneous effective permittivity ? and permeability µ, which become negative over an operating frequency range. At this frequency, direction of propagation is reversed. In this paper we demonstrate a polarization independent negative index metamaterial(NIM) at microwave frequencies. A negative-index is verified by using the retrieval procedure. This paper demonstrates the method of parameter extraction of negative index metamaterial with the help of matlab code. Backward wave propagation is observed in the numerical simulations at frequencies. The metamaterial used here is thin wire, Split ring resonator(SRR) and combination of SRR and two open complementary SRR(OCSRR). These structures are simulated and parameter extraction proves that the effective permittivity and permeability becomes negative over an operating frequency range.
