Abstract
We propose the concept of hyperbolic wires that overcome the actual limitation of metal-insulator-metal (MIM) patch antennas in terms of electromagnetic confinement and efficiency. The use of hyperbolic metamaterials allows one to realize miniaturized resonators sustaining bulk plasmon polaritons squeezed to only one-hundredth of the wavelength. Beyond this tenfold size reduction compared to MIM antennas, we propose a model allowing one to scale the resonant frequencies of hyperbolic wires over a broad spectral range by controlling the filling ratio in metals and dielectrics.
