A left-handed transmission band is observed at the frequencies where both dielectric permittivity and magnetic permeability are negative. The reflection characteristics of ordered and disordered LHMs are studied. The two-dimensional LHM structure is verified to have a negative refractive index. We employed three different methods to observe negative refraction: the beam shift method, refraction through wedge-shaped negative-index metamaterial, and phase-shift experiments.EnglishMetamaterialLeft-handed materialSplit-ring resonatorNegative permeabilityNegative refractionNegative phase velocityDisorderImpedance matchingMetamaterials with negative permeability and negative refractive index: Experiments and simulationsArticle10.1088/1464-4258/9/9/S041741-3567
