## Abstract We experimentally demonstrate negative refraction imaging at microwave frequencies by a threeβdimensional (3D) metamaterial with simple cubic unit structure, which is fabricated based on the electronic textile technology.A fourβlayer metamaterial sample was tested in a series of experim

## Abstract Metamaterial of twisted metallic foil pairs is proposed. Resonances are illustrated in both transmission and reflection. Negative refraction index can be realized by chiral configuration of this metamaterial. Parallel and antiparallel surface currents form magnetic and electric dipoles.
## Abstract We derive and compare the wave properties of transmissionβlineβbased negative refractive index metamaterials and their transmission line matrix (TLM) models. The TLM networks are computational replica of reactively loaded periodic structures that support backward waves and constitute ar
