Welcome to the UPF Digital Repository

The institutional repository collects, disseminates and preserves, in digital form, the intellectual output that results from the academic and research activity of the UPF and also the scientific magazines and the institutional publications. Its purpose is to increase the impact of research done at the UPF and its intellectual memory.

    A barefaced terrain scattering model for oil sand exploration will enable the discrimination of different terrain types using incoherent polarimetric decomposition. We use computer electromagnetic modeling with finite ...
  • Amiri, A.; Borda Fortuny, Cristina; Tong, Kin-Fai (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    Two different reconfigurable techniques for spectrum-monitoring antenna are presented. The first method inserts high-performance RF-MEMS switches along the microstrip feed line and back slot of a Vivaldi antenna ...
