Abstract :
A simplified structure made of periodic array of cross cut-wire pairs (CCWPs), printed on only one side of a dielectric substrate, is introduced. This simple negative refractive index (NRI) metamaterial is responsive to arbitrarily linearly polarized incident waves, which supports both symmetric and antisymmetric resonance modes, offering a very wide double-negative (DNG) passband with low losses. The superior performance of this 2-D isotropic inclusion is investigated both numerically and experimentally. The influence of the structure parameters on the magnetic response is studied in detail.
