A new units of two-dimensional meta-materials

A method of designing a single side left-handed structure based on the integration of electric resonator and magnetic resonator is proposed in this paper. The left-handed units are placed on one side of the substrate, and then make them arranged in periodic structures. The results of HFSS software simulation and a series of effective electromagnetic parameters extraction show that the left-handed structure exhibits negative effective permittivity and permeability in two dimension, in the first dimension, frequency range is 8.2-14.9GHz, in the second dimension, 8.5-14GHz, Its relative bandwidth reaches 56% and 49%, and the unit electrical length and loss are small in the same type of structures. This new structure lays a foundation for left-handed metamaterials widely used.
