A Uband Lefthanded Metamaterial Based on Twolayered SRR Structure
A Uband lefthanded metamaterial is designed and simulated to obtain the scattering parameters after the dimensions are estimated according to the transimission line theory of the lefthanded metamaterial. Furthermore, the properties of transmission and the negative electromagnetic parameters are analyzed after effective permittivity; effective permeability and refraction index are calculated by the Smith parameter retrieval method. The results show that the proposed lefthanded metamaterial structure behaviours the negative refraction characteristic while the real parts of effective permittivity and effective permeability are both negative in 48.8~59.9 GHz band. Thus, the existence of the lefthanded metamaterial in Uband is demonstrated,and it is of great reference significance to research on metamaterials in higher band.
