An ENZ metamaterial is engineered using a parallel plate plasmonic waveguide working near the cut-off of the transverse electric TE1 mode. The ENZ region can be displaced to different wavelengths when the electrical width of the sandwiched dielectric is changed. Several converging lenses are designed at λ0 = 474.9 nm with a focal length of 10.75λ0: a smooth concave, zoned and graded refractive index (GRIN) lens. It is demonstrated that the best performance in terms of the focal length and volume reduction is achieved with the GRIN design, achieving values of 10.23λ0 and ~52%, respectively.
