    • Zoned near-zero refractive index fishnet lens antenna: steering millimeter waves 

      Pacheco-Peña, Víctor Upna; Orazbayev, Bakhtiyar Upna; Beaskoetxea Gartzia, Unai Upna; Beruete Díaz, Miguel Upna; Navarro Cía, Miguel Upna (AIP Publishing, 2014)   Artículo / Artikulua  OpenAccess
      A zoned fishnet metamaterial lens is designed, fabricated, and experimentally demonstrated at millimeter wavelengths to work as a negative near-zero refractive index lens suitable for compact lens antenna configurations. ...
    • ε-near-zero (ENZ) graded index quasi-optical devices: steering and splitting millimeter waves 

      Pacheco-Peña, Víctor Upna; Torres Landívar, Víctor Upna; Beruete Díaz, Miguel Upna; Navarro Cía, Miguel Upna; Engheta, Nader (IOP Publishing, 2014)   Artículo / Artikulua  OpenAccess
      Graded index ε near-zero (GRIN-ENZ) quasi-optical components such as beam steerers and power splitters are designed, simulated and analyzed. The GRIN-ENZ medium is realized using stacked narrow hollow waveguides whose ...
