• Keller’s theorem revisited 

      Ortiz, Guillermo P.; Mochán, W. Luis (IOP Publishing Ltd, 2018)
      Keller’s theorem relates the components of the macroscopic dielectric response of a binary twodimensional composite system with those of the reciprocal system obtained by interchanging its components. We present a derivation ...
    • Optical and electrical properties of nanostructured metallic electrical contacts 

      Toranzos, Victor J.; Ortiz, Guillermo P.; Mochán, W. Luis; Zerbino, Jorge O. (IOP Publishing Ltd, 2017)
      We study the optical and electrical properties of silver films with a graded thickness obtained through metallic evaporation in vacuum on a tilted substrate to evaluate their use as semitransparent electrical contacts. We ...
