    • Linealización de resonadores superconductores 

      Padilla Díaz, Alberto (Universitat Politècnica de Catalunya, 2008-07-24)
      Projecte/Treball Final de Carrera
      Accés obert
      Los materiales superconductores de alta temperatura (HTS) permiten realizar dispositivos de muy altas prestaciones y dimensiones muy reducidas. Sin embargo, estos materiales presentan un comportamiento no-lineal ...
    • Lossy filter synthesis of L-band planar filters using novel software 

      Padilla Díaz, Alberto; Mateu Mateu, Jordi; Collado Gómez, Juan Carlos; Rocas Cantenys, Eduard; Ernst, Cristoph; Rius Casals, Juan Manuel; Tamayo Palau, José María; O'Callaghan Castellà, Juan Manuel (2011)
