    • Fractal FSS: a novel dual band frequency selective surface 

      Romeu Robert, Jordi; Rahmat-Samii, Yahya (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2000-07-31)
      Article
      Accés obert
      The multiband properties of self-similar fractals can be advantageously exploited to design multiband frequency selective surfaces (FSS). A Sierpinski dipole FSS has been analyzed and measured and the results show an ...

    • The visibility function in interferometric aperture synthesis radiometry 

      Corbella Sanahuja, Ignasi; Duffo Ubeda, Núria; Vall-Llossera Ferran, Mercedes Magdalena; Camps Carmona, Adriano José; Torres Torres, Francisco (Institute of Electrical and Electronics Engineers (IEEE), 2004-08)
      Article
      Accés obert
      The fundamental equation of interferometric aperture synthesis radiometry is revised to include full antenna pattern characterization and receivers' interaction. It is shown that the cross correlation between the output ...
