Abstract:
We introduce an improved and simplified structure made of periodic arrays of pairs of H-shaped
metallic wires that offer a potentially simpler approach in building negative-index materials. Using
simulations and microwave experiments, we have investigated the negative-index n properties of
these structures. We have measured experimentally both the transmittance and the reflectance
properties and found unambiguously that a negative refractive index with Ren0 and Imn
Ren. The same is true for and . Our results show that H-shaped wire pairs can be used very
effectively in producing materials with negative refractive indices.
