    • 77-GHz high-gain bull’s-eye antenna with sinusoidal profile 

      Beaskoetxea Gartzia, Unai Upna; Pacheco Peña, Víctor Upna; Orazbayev, Bakhtiyar Upna; Akalin, Tahsin; Maci, Stefano; Navarro Cía, Miguel Upna (IEEE, 2015)   Artículo / Artikulua  OpenAccess
      A high-gain Bull’s-Eye leaky-wave horn antenna working at 77 GHz with sinusoidal profile has been designed, fabricated, and experimentally measured. The influence of the number of periods on the gain and beamwidth is ...
    • Focus on terahertz plasmonics 

      Rahm, Marco; Nahata, Ajay; Akalin, Tahsin; Beruete Díaz, Miguel Upna; Sorolla Ayza, Mario Upna (IOP Publishing, 2015)   Artículo / Artikulua  OpenAccess
      Plasmonics is one of the growing fields in modern photonics that has garnered increasing interest over the last few years. In this focus issue, the specific challenges concerning terahertz plasmonics have been addressed ...
    • Low profile THz periodic leaky-wave antenna 

      Beaskoetxea Gartzia, Unai Upna; Beruete Díaz, Miguel Upna; Rodríguez Ulibarri, Pablo Upna; Etayo Salinas, David Upna; Sorolla Ayza, Mario Upna; Navarro Cía, Miguel Upna; 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 ...
