Miniaturizing optical antennas using hyperbolic metamaterial wires

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