We report our experimental results on two-dimensional left-handed metamaterials (LHM) exhibiting negative refraction and subwavelength imaging. Transmission and reflection spectra of LHM are studied and a left-handed transmission band is observed at the frequencies where both dielectric permittivity

Abstract
We experimentally demonstrate negative refraction imaging at microwave frequencies by a three‐dimensional (3D) metamaterial with simple cubic unit structure, which is fabricated based on the electronic textile technology.A four‐layer metamaterial sample was tested in a series of experiments. The experimental result of the characteristic plasma frequency of the metamaterial was in good agreement with the theoretical result. The fabrication approach for 3D metamaterial may find many novel applications at microwave frequencies. © 2010 Wiley Periodicals, Inc.
