In particular, we demonstate the true left handed behavior of a 2D composite metamaterial, by analyzing the electric and magnetic response of the material components systematically. The negative refraction, subwavelength focusing, and flat lens phenomena using 2D dielectric photonic crystals are also presented.EnglishLeft-handed mediumMetamaterialNegative phase velocityNegative refractionPhotonic crystalSplit ring resonatorCrystalsFocusingRefractionRefractive indexTwo dimensionalLeft-handed mediumMetamaterialsNegative phase velocityNegative refractionPhotonic crystalsSplit ring resonatorsComposite materialsDevelopment of left-handed composite materials and negative refracting photonic crystals with subwavelength focusingConference Paper10.1117/12.630087
