      Pacheco Peña, Víctor Upna; Torres Landívar, Víctor Upna; Orazbayev, Bakhtiyar Upna; Beruete Díaz, Miguel Upna; Navarro Cía, Miguel Upna; Sorolla Ayza, Mario Upna; Engheta, Nader (AIP Publishing, 2014)   Artículo / Artikulua  OpenAccess
      An all-metallic steerable beam antenna composed of an ε-near-zero (ENZ) metamaterial lens is experimentally demonstrated at 144 GHz (λ0 = 2.083 mm). The ENZ lens is realized by an array of narrow hollow rectangular waveguides ...
    • 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 ...
