Constitutive parameter analysis of left-handed dual-star split-ring resonator metamaterial for homogeneous infinite slab

A new shaped backward wave periodic dual-star split-ring resonator (DSSRR) is proposed based on the equivalent transmission line theory. The proposed artificial DSSRR design structure produces a wide band from 7.5 to 9.5 GHz, and very high rejection (47 dB) with sharp cut-offs in the forbidden band....
