Abstract: In this paper a slab of stacked near cut-off rectangular waveguides emulating an ε-near-zero (ENZ) artificial material is designed to behave as a bi-concave symmetric lens. First, a rectangular narrow hollow waveguide is simulated in order to show how such device can be used to mimic an ENZ medium. Afterwards, a Graded Index ENZ structure emulating a symmetric 7λ0 input and output focal length converging bi-concave lens is designed working at 100 GHz. © 2013 EurAAP.
