    • Compact dual-band terahertz quarter-wave plate metasurface 

      Torres Landívar, Víctor Upna; Etayo Salinas, David Upna; Ortuño Molinero, Rubén Upna; Navarro Cía, Miguel Upna Orcid; Beruete Díaz, Miguel Upna Orcid (IEEE, 2014)   Artículo / Artikulua  OpenAccess
      A dual-band quarter-wave plate based on a modified extraordinary transmission hole array is numerically analyzed and experimentally demonstrated at terahertz frequencies. To control independently orthogonal polarizations, ...
    • Full three-dimensional isotropic transformation media 

      García Meca, Carlos; Ortuño Molinero, Rubén Upna; Martí, J.; Martínez, Alejandro (IOP Publishing, 2014)   Artículo / Artikulua  OpenAccess
      We present a method that enables the implementation of full three-dimensional (3D) transformation media with minimized anisotropy. It is based on a special kind of shape-preserving mapping and a subsequent optimization ...
    • Mid-infrared plasmonic inductors: enhancing inductance with meandering lines 

      Torres Landívar, Víctor Upna; Ortuño Molinero, Rubén Upna; Rodríguez Ulibarri, Pablo Upna Orcid; Beruete Díaz, Miguel Upna Orcid; Sorolla Ayza, Mario Upna; Griol, Amadeu; Martínez, Alejandro; Navarro Cía, Miguel Upna Orcid (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 ...
