• Mid-infrared plasmonic inductors: enhancing inductance with meandering lines 

      Torres Landívar, Víctor Upna; Ortuño Molinero, Rubén Upna; Rodríguez Ulibarri, Pablo Upna; Beruete Díaz, Miguel Upna; Sorolla Ayza, Mario Upna; Griol, Amadeu; Martínez, Alejandro; Navarro Cía, Miguel Upna (Nature Publishing Group, 2014)   Artículo / Artikulua  OpenAccess
      We present a mid-infrared inductor that when applied to an extraordinary transmission hole array produces a strong redshift of the resonant peak accompanied by an unprecedented enlargement of the operation bandwidth. The ...
    • Plasmonics and metamaterials at terahertz frequencies 

      Torres Landívar, Víctor Upna (2014)   Tesis doctoral / Doktoretza tesia  OpenAccess
      The research presented in this manuscript falls under the framework of metamaterials and plasmonics. It is mainly focused on applications at terahertz (THz) frequencies, a spectral band located between microwaves and ...
    • Steering surface plasmons with a graded index dielectric medium 

      Beruete Díaz, Miguel Upna; Pacheco-Peña, Víctor Upna (IOP Publishing, 2018)   Artículo / Artikulua
      The arbitrary control of surface plasmon (SP) propagation has become an intense research topic for several decades. This is due to the fact that they can be used in a variety of fields such as optical trapping, nanoantennas ...
