    • Análisis de geometrías fractales para resonadores microstrip 

      Extremera Extremera, Manuel Jesus (Universitat Politècnica de Catalunya, 2016-02-25)
      Projecte/Treball Final de Carrera
      Accés obert
      Usage and popularity growth of communications satellites has increased the interest on filter synthesis research. Nowadays, the improvement of the trade-off between size, weight, cost and performance is the golden rule. ...

    • Characterization of EMI filters based on metamaterials 

      Gil Galí, Ignacio; Fernández García, Raúl; Vives, Yolanda; Jauregui Tellería, Ricardo; Silva Martínez, Fernando (2009-06)
      Comunicació de congrés
      Accés obert
      This paper analyzes the behavior of EMI filters based on metamaterials. The filters are developed by means of sub-wavelength resonators and designed to have notch-type attenuation in the 2.45 GHz band. Two types of filters ...
