    • 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, ...
    • Low profile THz periodic leaky-wave antenna 

      Beaskoetxea Gartzia, Unai Upna Orcid; Beruete Díaz, Miguel Upna Orcid; Rodríguez Ulibarri, Pablo Upna Orcid; Etayo Salinas, David Upna; Sorolla Ayza, Mario Upna; Navarro Cía, Miguel Upna Orcid; Zehar, Mokhtar; Blary, Karine; Chahadih, Abdallah; Han, Xiang-Lei; Akalin, Tahsin (IEEE, 2014)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      In this work, a 0.566THz flat leaky-wave antenna, consisting of a central λ0/2 slot surrounded by straight parallel wedge corrugations, is numerically and experimentally analyzed. Simulations show a moderately high gain ...
    • Mapping the conductivity of graphene with electrical resistance tomography 

      Cultrera, Alessandro; Serazio, Danilo; Zurutuza, Amaia; Centeno, Alba; Txoperena, Ohiana; Etayo Salinas, David Upna; Cordón, Álvaro; Redo Sánchez, Albert; Arnedo Gil, Israel Upna Orcid; Ortolano, Massimo; Callegaro, Luca (Nature Research, 2019)   Artículo / Artikulua  OpenAccess
      Electronic applications of large-area graphene films require rapid and accurate methods to map their electrical properties. Here we present the first electrical resistance tomography (ERT) measurements on large-area graphene ...
    • New developments in the THz field for imaging applications 

      Etayo Salinas, David Upna (2014)   Tesis doctoral / Doktoretza tesia  OpenAccess
      Con esta tesis se pretende avanzar en el desarrollo de la tecnología de terahercios (THz) dentro del campo de las aplicaciones de imagen. Actualmente, los THz se presentan como un rango frecuencial muy interesante para ...
