Here we discuss the possibility of using ε-near-zero (ENZ) metamaterials for lensing and Fourier transforming. Owing to the possibility of having ENZ metamaterials in different wavelength regimes, the concepts shown here can be utilized at any frequency bands in which such materials can be constructed.6 p.application/pdfeng© 2012 American Physical SocietyMetamaterialsFourier transformingENZ metamaterialsinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/openAccess
