The scope of this paper is to design and simulate a novel circular split ring structure having simultaneous negative permittivity and permeability so called double negative metamaterial or left handed material. The DNG structure consists of five circular split ring resonators on one side of dielectric medium and a couple of circular wires on other side. The complex permittivity, permeability, impedance and refractive index are determined from simulated Scattering parameters using direct retrieval method. Simulations of DNG structure are carried out using CST MWS. MATLAB is used for verification of negative values of structure’s parameter.
