Abstract

We present, design and analyze a novel planar left-handed (LH) metamaterial in the microwave region. This metamaterial is composed of only cut metallic wires and is used under normal-to-plane incidence. Using finite element method (FEM) based simulations and microwave experiments, we have investigated the material properties of the structure. Simultaneous negative values are observed for the permittivity epsiv and permeability mu by the inversion method from the transmission and reflection responses. A negative index n is verified in a bulk prism engineered by stacking several layers of the metamaterial. Our work demonstrates the feasibility of a LH metamaterial composed of only cut wires.
