      Accés obert
      The gate-controllable complex conductivity of graphene offers unprecedented opportunities for reconfigurable plasmonics at terahertz and mid-infrared frequencies. However, the requirement of a gating electrode close to ...
    • Teraherz subsurface imaging system 

      Nova, Enrique; Abril, Jordi; Guardiola Garcia, Marta; Capdevila Cascante, Santiago; Broquetas Ibars, Antoni; Romeu Robert, Jordi; Jofre Roca, Lluís (2010)
      Text en actes de congrés
      Accés obert
      A subsurface imaging system based on a terahertz time-domain spectrometer (THz-TDS) is described in this paper. The system performance has been simulated in terms of spatial resolution, penetration capabilities and SNR. ...
    • The “challenging” world of Terahertz radiation and imaging 

      Jofre Roca, Lluís; Romeu Robert, Jordi; Capdevila Cascante, Santiago; Abril, Jordi; Nova, Enrique; Alonso, Maria (2011)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      THz propagation through materials may reveal unique macroscopic and physical properties of their internal structure without the damage associated with ionizing radiation. The generation, radiation, and detection of THz ...
    • Toward 3D UWB tomographie imaging system for breast tumor detection 

      Guardiola Garcia, Marta; Jofre Roca, Lluís; Capdevila Cascante, Santiago; Blanch Boris, Sebastián; Romeu Robert, Jordi (2010)
      Text en actes de congrés
      Accés obert
      A novel 3D tomographic algorithm for short range cylindrical geometries using UWB frequency range is presented. The algorithm has been applied to breast tumor detection, nevertheless, its non application-specific character ...
