    • 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 ...
    • New regimes to achieve enhanced transmission through subwavelength hole arrays 

      Navarro Cía, Miguel Upna; Beruete Díaz, Miguel Upna; Sorolla Ayza, Mario Upna (2011)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      In this communication we present millimetre- and THz-waves experimental confirmation of enhanced transmission through subwavelength hole arrays with rectangular lattice when the incident electric field is parallel to ...
    • A slow light fishnet-like absorber in the millimeter-wave range 

      Navarro Cía, Miguel Upna; Torres Landívar, Víctor Upna; Beruete Díaz, Miguel Upna; Sorolla Ayza, Mario Upna (EMW Publishing, 2011)   Artículo / Artikulua  OpenAccess
      A novel route to achieve a narrowband free-space electromagnetic absorber in any range of the spectrum based on stacked subwavelength hole arrays is proposed. The absorption is obtained by means of a slow light mode inside ...
    • Strong lateral displacement in polarization anisotropic extraordinary transmission metamaterial 

      Beruete Díaz, Miguel Upna; Navarro Cía, Miguel Upna; Sorolla Ayza, Mario Upna (IOP Publishing Ltd, 2010)   Artículo / Artikulua  OpenAccess
      In this paper, a deep numerical as well as experimental study of the anisotropy response of extraordinary transmission metamaterials constructed by stacking subwavelength hole arrays is presented. Two-dimensional (2D) ...
