- 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 琯 and permeability μ 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. ©2009 IEEE.
