Abstract:The layout of this research work is to simulate a novel opposite C-shape unit cell at resonance frequency of 12 GHz, having negative permittivity and permeability, which is often, referred to as double negative metamaterial (DNG) or left-handed material. The DNG shape includes opposite C resonators on one side of dielectric medium and same shape on other side. The Scattering parameters as well as permittivity, permeability and refractive index are determined from the simulated Simulations of DNG structure using Computer simulation technology (CST) in microwave studio (MWS). For verification of negative values of structure's parameter, MATLAB was used. This is a novel and promising design approach in the world of electromagnetics due to its simplicity, scalability and characteristics of double-negative material.
