    • IconAnalytical method to estimate the complex permittivity of oil samples  [Article]

      Su, Lijuan; Mata Contreras, Javier; Vélez, Paris; Fernández Prieto, Armando; Martín, Ferrán (MDPI, 2018)
      In this paper, an analytical method to estimate the complex dielectric constant of liquids is presented. The method is based on the measurement of the transmission coefficient in an embedded microstrip line loaded with ...
    • IconBalanced-To-Balanced Microstrip Diplexer Based on Magnetically Coupled Resonators  [Article]

      Fernández Prieto, Armando; Lujambio, Aintzane; Martel Villagrán, Jesús; Medina Mena, Francisco; Martín, Ferrán; Rodríguez Boix, Rafael (Institute of Electrical and Electronics Engineers, 2018)
      Two balanced-To-balanced planar diplexers based on magnetically coupled microstrip resonators are proposed in this paper. For the first prototype, each channel/differential-output is composed of a second order single-band ...
    • IconClassical Physics and the Bounds of Quantum Correlations  [Article]

      Velázquez Ahumada, María del Castillo; Baltanás, José P.; Frustaglia, D.; Fernández Prieto, Armando; Lujambio, Aintzane; Losada, Vicente; Freire Rosales, Manuel José (American Physical Society, 2016-06-24)
      A unifying principle explaining the numerical bounds of quantum correlations remains elusive, despite the efforts devoted to identifying it. Here, we show that these bounds are indeed not exclusive to quantum theory: for ...
    • IconDual-band differential filter using broad-band common-mode rejection artificial transmission line  [Article]

      Mesa Ledesma, Francisco Luis; Qian, Shilong; Hong, Jia-Sheng; Naqui, Jordi; Martín, Ferrán; Fernández Prieto, Armando; Medina Mena, Francisco; Martel Villagrán, Jesús (2013)
    • IconEffects of inter-resonator coupling in split ring resonator loaded metamaterial transmission lines  [Article]

      Naqui, Jordi; Fernández Prieto, Armando; Mesa Ledesma, Francisco Luis; Medina Mena, Francisco; Martín, F. (American Institute of Physics, 2014)
      This paper investigates the effects of inter-resonator coupling in metamaterial transmission lines loaded with split ring resonators (SRRs). The study is performed from Bloch mode theory applied to the multiport equivalent ...
    • IconLíneas de transmisión artificiales para señales diferenciales con rechazo de modo común  [Final Degree Work]

      Reina Campo, Pablo (2017)
      En el campo de las comunicaciones eléctricas, el uso del espectro de microondas se ha ido generalizando progresivamente, encontrándose en este rango de frecuencias muchas de las aplicaciones que dominan la tecnología en ...
    • IconMicrostrip circuit analog of a complex diffraction phenomenon  [Article]

      Fernández Prieto, Armando; Medina Mena, Francisco; Mesa Ledesma, Francisco Luis (American Institute of Physics, 2009)
      This letter presents a methodology to reproduce at microwave frequencies the physical behavior of certain diffraction structures that have been investigated in the optics community. The methodology will be exemplified with ...
    • IconThe Beauty of Symmetry: Common-mode rejection filters for high-speed interconnects and balanced microwave circuits  [Article]

      Martin, Ferran; Naqui, Jordi; Fernández Prieto, Armando; Vélez, Paris; Bonache, Jordi; Martel Villagrán, Jesús; Medina Mena, Francisco (Institute of Electrical and Electronics Engineers (IEEE), 2017-02)
      Common-mode rejection filters operating at microwave frequencies have been the subject of intensive research activity in the last decade. These filters are of interest for the suppression of common-mode noise in high-speed ...
