    • Dielectric properties of milk during ultra-heat treatment 

      Muñoz, Israel; Gou, Pere; Picouet, Pierre A.; Barlabe Dalmau, Antoni; Felipe, Xavier (Elsevier, 2018-02-01)
      Article
      Accés obert
      Dielectric properties are important for predicting dielectric heating of foodstuffs. The dielectric properties of three types of milk (raw, skimmed and concentrated non-fat) were analyzed at high frequencies between 10 MHz ...

    • Generalized transverse resonance analysis of planar discontinuities considering the edge effect 

      Barlabe Dalmau, Antoni; Comerón Tejero, Adolfo; Pradell i Cara, Lluís (2000-12)
      Article
      Accés obert
      Abstract: Mode-matching related techniques such as the Generalized Transverse Resonance Method (GTR) suffer from the relative convergence phenomenon. To reduce its influence, we present a technique consisting of the ...
