  • A plasmonic accuracy biosensor using a single laser diode 

    Bañares Palacios, Paula (Universitat Politècnica de Catalunya, 2016-09-07)
    Master thesis
    Open Access
    A theoretical model was implemented to obtain the total specular reflection of a variable external multicavity for out of normal incidence and different polarisations. The model was theoretically and experimentally validated ...
  • Design and analysis an array of Patch Antenna at 2.4GHz with circular polarization 

    Domènech Ruiz, Rubén (Universitat Politècnica de Catalunya, 2016-01)
    Bachelor thesis
    Open Access
    Covenantee:  Západočeská univerzita v Plzni
    We are in an industry where everything changes very quickly, and if we focus on the design of antennas we see that increasingly we are looking for smaller dimensions with better features. In this issue we can highlight the ...
  • Effect of flexoelectricity on elasticity characterization by nanoindentation 

    Shaikh, Salik Firdos (Universitat Politècnica de Catalunya, 2017-06-16)
    Master thesis
    Open Access
    Flexoelectricity is a very common phenomenon in dielectrics and is a size-dependent electromechanical mechanism coupling polarization and strain gradient. Flexoelectric effect is significant due to higher strain gradients ...
  • Electrically polarized hydroxyapatite: influence of the polarization process on the microstructure and properties 

    Sans Milà, Jordi; Llorca Piqué, Jordi; Sanz, Vanesa; Puiggalí Bellalta, Jordi; Turón Dols, Pau; Alemán Llansó, Carlos (2019-11-19)
    Article
    Open Access
    Semipermanently polarized hydroxyapatite, named SP/HAp(w), is obtained by applying a constant dc electric field of 1–10 kV/cm at 300–850 °C to the samples previously sintered in water vapor, while permanently polarized ...
  • Flexoelectricity in nanobeams under torsion 

    Moliner Martinez, Jordi (Universitat Politècnica de Catalunya, 2016-06-23)
    Bachelor thesis
    Open Access
    We will study the effect of flexoelectricity in the electromechanical response of nanobeams under torsion.
  • Imaging of biomedical data using a multiplicative regularized contrast source inversion method 

    Abubakar, A.; Van den Berg, Peter M.; Mallorquí Franquet, Jordi Joan (2002-07)
    Article
    Open Access
    In this paper, the recently developed multiplicative regularized contrast source inversion method is applied to microwave biomedical applications. The inversion method is fully iterative and avoids solving any forward ...
  • Method to distinguish between space-charge and dipolar relaxation in the TSDC spectra of polyethylene electrical insulation 

    Orrit Prat, Jordi; Cañadas Lorenzo, Juan Carlos; Sellarès González, Jordi; Belana Punseti, Juan (2010)
    Conference lecture
    Open Access
    Medium-voltage cross-linked polyethylene (MV-XLPE) cables have an important role in the electrical power distribution system. For this reason, the study of XLPE insulation may lead to improve cable features and lifetime. ...
  • Molecular dynamics simulations of polarization domains and flexoelectricity in BaTiO3 

    Abarca Morales, Edgar (Universitat Politècnica de Catalunya, 2018-06-27)
    Master thesis
    Open Access
    This thesis is a part of a project started in December 2016 in collaboration with Prof. Jorge Alcalá Cabrelles (UPC, Barcelona) and Dr. Jan Ocenasek (ZCU institute, Czech Republic) aiming to perform piezoelectric and ...
  • Soil Moisture estimation using polarimetric SAR 

    Closa Tarres, Marc (Universitat Politècnica de Catalunya, 2019-08)
    Bachelor thesis
    Open Access
    Covenantee:  University of Massachusetts at Amherst
    La humedad del suelo es una variable primaria para comprender el ciclo hidrológico global. En las disciplinas de ciencias de la Tierra y del medio ambiente, la estimación de este parámetro en alta resolución siempre ha ...
  • State of charge dependency of the overvoltage generated in commercial Li-ion cells 

    Ovejas Benedicto, Victòria Júlia; Cuadras Tomàs, Àngel (2019-04-01)
    Article
    Restricted access - publisher's policy
    The overvoltage that is produced in the cells under operation limits the capacity and power they can deliver. A detailed study about the mechanisms that contribute to that overvoltage—and thus to their lifetime—is required ...
  • Static and dynamic amplitude modulation of light in a twisted nematic liquid crystal display 

    Vilardy Ortiz, Juan Manuel; Millán Garcia-Varela, M. Sagrario; Pérez Cabré, Elisabet (International Society for Photo-Optical Instrumentation Engineers (SPIE), 2013)
    Conference lecture
    Restricted access - publisher's policy
    A SLM has been experimentally characterized in terms of amplitude modulation versus the gray level distribution (input signal) electronically addressed to the pixelated display in two conditions: input constant with time, ...
  • Statistical modeling of dual-polarized MIMO land mobile satellite channels 

    Liolis, K.P.; Gómez Vilardebó, Jesús; Casini, Enrico; Pérez Neira, Ana Isabel (2010-11)
    Article
    Open Access
    This Letter addresses the statistical modeling of dual-polarized MIMO-LMS fading channels. In the absence of accurate experimental results, a statistical model for the characterization of MIMO-LMS channels is proposed ...
