Veselago pointed out that a material exhibiting negative values of dielectric permittivity (ε) and magnetic permeability (μ) would have a negative refractive index [1]. Generally speaking, the dielectric permittivity (ε) and the magnetic permeability (μ) are both positive for natural materials. In fact it is possible to obtain negative values for ε and μ by utilizing proper designs of metamaterials. Left-handed electromagnetism and negative refraction are achievable with artificially structured metamaterials exhibiting negative values of permittivity and permeability simultaneously at a certain frequency region. The first steps to realize these novel type of materials were taken by Smith et al., where they were able to observe a left-handed propagation band at frequencies where both dielectric permittivity and magnetic permeability of the composite metamaterial are negative [2]. Soon after, left-handed metamaterials with an effective negative index of refraction are successfully demonstrated by various groups [3].EnglishComposite metamaterialsDielectric permittivitiesFrequency regionsLeft handed metamaterialNatural materialsNegative index of refractionNegative refractionsNegative refractive indexNegative valuesProper designCapillarityElectronic equipmentFluorine containing polymersLight refractionMagnetic permeabilityMetamaterialsPermanent magnetsPermittivityRefractionRefractive indexDielectric materialsConference Paper10.1109/LEOS.2009.5343435
