      Navarro Cía, Miguel Upna; Beruete Díaz, Miguel Upna; Sorolla Ayza, Mario Upna; Campillo, Igor (AIP Publishing, 2009)   Artículo / Artikulua  OpenAccess
      In this letter we present simulation and experimental results of a left-handed converging biconcave metallic lens made of stacked subwavelength hole arrays SSHAs working in the millimeter wave range with additional ...
    • Extraordinary transmission and left-handed propagation in miniaturized stacks of doubly periodic subwavelength hole arrays 

      Beruete Díaz, Miguel Upna; Sorolla Ayza, Mario Upna; Navarro Cía, Miguel Upna; Falcone Lanas, Francisco Javier Upna; Campillo, Igor; Lomakin, Vitaliy (Optical Society of America, 2007)   Artículo / Artikulua  OpenAccess
      Metallic plates embedded between dielectric slabs and perforated by rectangular arrays of subwavelength holes with a dense periodicity in one of the directions support extraordinary transmission (ET) phenomena, viz. strong ...
    • Left-handed extraordinary optical transmission through a photonic crystal of subwavelength hole arrays 

      Beruete Díaz, Miguel Upna; Sorolla Ayza, Mario Upna; Campillo, Igor (Optical Society of America, 2006)   Artículo / Artikulua  OpenAccess
      Metamaterial structures are artificial materials that show unconventional electromagnetic properties such as photonic band-gap, extraordinary optical transmission and left-handed propagation. Up to now, relations of photonic ...
    • Negative refraction in a prism made of stacked subwavelength hole arrays 

      Navarro Cía, Miguel Upna; Beruete Díaz, Miguel Upna; Sorolla Ayza, Mario Upna; Campillo, Igor (Optical Society of America, 2008)   Artículo / Artikulua  OpenAccess
      Metamaterial structures are artificial materials that show unconventional electromagnetic properties such as negative refraction index, perfect lenses, and invisibility. However, losses are one of the big challenges to be ...
    • Negative refraction through an extraordinary transmission left-handed metamaterial slab

      Polarization rotation or selection appears in materials with optical activity, or those with Faraday effect, or in liquid crystals. In this letter we present a structure, with an analogous response, using stacked ...
    • Polarized left-handed extraordinary optical transmission of subterahertz waves 

      Beruete Díaz, Miguel Upna; Navarro Cía, Miguel Upna; Sorolla Ayza, Mario Upna; Campillo, Igor (Optical Society of America, 2007)   Artículo / Artikulua  OpenAccess
      In this paper we design and measure a metamaterial polarizing device working in the sub-terahertz range. The polarizer is based on a modified version of our previous miniaturized Stacked Hole Array (SHA) structure, an ...
