    • Labyrinth metasurface for biosensing applications: numerical study on the new paradigm of metageometries 

      Jáuregui López, Irati; Rodríguez Ulibarri, Pablo Upna; Kuznetsov, Sergei A.; Quemada Mayoral, Carlos; Beruete Díaz, Miguel Upna (MDPI, 2019)   Artículo / Artikulua  OpenAccess
      The use of metasurfaces operating in the terahertz regime as biosensor devices has attracted increased interest in recent years due to their enhanced sensitivity and more accurate detection capability. Typical designs are ...
    • A water content continuous monitoring of grapevine xylem tissue using a portable low-power cost-effective FMCW radar 

      Quemada Mayoral, Carlos; García González, Cebrián; Iriarte Galarregui, Juan Carlos Upna; Marín Ederra, Diana; Gastón Beraza, Diego; Miranda Jiménez, Carlos Upna; Gonzalo García, Ramón Upna; Maestrojuán Biurrun, Itziar Upna; Santesteban García, Gonzaga Upna; Ederra Urzainqui, Íñigo Upna (IEEE, 2019)   Artículo / Artikulua
      This paper presents the real-time monitoring of a grapevine’s water content that flows up through the xylem tissue by means of a frequency-modulated continuous-wave (FMCW) radar. The application of an optimization process, ...
