  • 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 ...
  • TFET-Based power management circuit for RF energy harvesting 

    Nunes Cavalheiro, David Manuel; Moll Echeto, Francisco de Borja; Valtchev, Stanimir (2016-11-14)
    Article
    Accés obert
    This paper proposes a Tunnel FET (TFET)-based power management circuit (PMC) for ultra-low power RF energy harvesting applications. In contrast with conventional thermionic devices, the band-to-band tunneling mechanism of ...
