The metamaterial structure is composed of periodic arrays of split-ring resonators and wire meshes and exhibits a left-handed propagation band at frequencies of negative permittivity and negative permeability. Negative refraction is verified using prism shaped LHM and also by beam-shifting method. Subwavelength focusing of a point source is achieved with a resolution of 0.13λ, through a flat LHM superlens.EnglishLeft-handed metamaterialMetamaterialsNegative refractive indexSuperlensMagnetic permeabilityMicrowave frequenciesPermittivityRefractionRefractive indexResonatorsComputer networksLight refractionMaterials scienceOpticsSubwavelength focusingComposite metamaterialsLeft handed (LH)Left-handed metamaterials (LHM)Metamaterial structuresMetamaterials (MTM)Negative permeabilityNegative permittivityNegative refractionsPeriodic arraysPoint sourcesSplit ring resonator (SRR)Subwavelength focussingSuper lensWire meshesComposite materialsElectronic equipmentNegative refraction and subwavelength focusing using left-handed composite metamaterialsConference Paper10.1117/12.777405
