Abstract

A parallel plate plasmonic waveguide is proposed in order to emulate the performance of apermittivity-near-zero metamaterial (ENZ) at optical wavelengths by working near the cut-off of the TE₁mode. It is shown that the ENZ region can be tuned by simply modifying the electrical width of the dielectric spacerof the plasmonic waveguide. Also, a graded index (GRIN) epsilon-near-zero lens working at λ₀=474.9 nm is designed by stacking 51 non-uniform plasmonic parallel plates, demonstrating numerically that this structure may be used to focus optical waves.
