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 left handed metamaterials and photonic crystals are also presented.EnglishLeft-handed mediumMetamaterialNegative phase velocityNegative refractionPhotonic crystalSplit ring resonatorComposite materialsElectromagnetismPhotonic crystalsRefractive indexWavelengthElectromagnetic propertiesLeft handed mediumNegative phase velocityNegative refractionSplit ring resonatorsOptical materialsConference Paper10.1117/12.723936
