    Imbert Villà, Marc; Papió, Anna; de Flaviis, Franco; Jofre Roca, Lluís; Romeu Robert, Jordi (2015-01-01)
    Article
    Open Access
    In this letter, a practical fabrication of a novel inhomogeneous gradient-index dielectric flat lens for millimeter-wave applications is presented. A previous theoretical design of a dielectric flat lens composed of different ...
  • Self-biased reconfigurable graphene stacks for terahertz plasmonics 

    Gomez Diaz, J. S.; Moldovan, C; Capdevila Cascante, Santiago; Romeu Robert, Jordi; Bernard, L. S.; Magrez, A; Ionescu, A. M.; Perruisseau Carrier, Julien (2015-03-01)
    Article
    Open Access
    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 ...
  • Volumetric testing parallel to the boundary surface for a nonconforming discretization of the electric-field integral equation 

    Úbeda Farré, Eduard; Rius Casals, Juan Manuel; Heldring, Alexander; Sekulic, Ivan (2015-07)
    Article
    Open Access
    The volumetric monopolar-RWG discretization of the electric-field integral equation (EFIE) imposes no continuity constraint across edges in the surface discretization around a closed conductor. The current is expanded with ...
  • Stochastic estimation of the Frobenius norm in the ACA convergence criterion 

    Heldring, Alexander; Úbeda Farré, Eduard; Rius Casals, Juan Manuel (2015-03-01)
    Article
    Open Access
    The adaptive cross approximation (ACA) algorithm has been used in many fast Integral Equation solvers for electromagnetic Radiation and Scattering problems. It efficiently computes a low rank approximation to the interaction ...

    A silicon lens antenna suited for future integrated terahertz arrays has been proposed recently. The antenna consists of an extended hemispherical silicon lens fed by a leaky-wave waveguide feed. The primary advantage is ...
  • Telefonía IP de banda ancha 

    Elias Fusté, Antonio (2005-02-28)
    Article
    Open Access
    La telefonía IP representará una auténtica revolución, la primera en 100 años de telefonía vocal fija. A nuestro entender, las dos palabras clave que definen los servicios de VoIP son: (1) “personalización”, concepto que ...
  • Las Redes de nueva generación 

    Elias Fusté, Antonio (2007-12-15)
    Article
    Open Access
    Las redes de nueva generación (NGN) van a obligar a concebir un nuevo tipo de regulación.
  • El Ingeniero desde el concepto de servicio 

    Elias Fusté, Antonio; Torres Torres, Francisco (1998-11-30)
    Article
    Open Access
    Las exigencias actuales del entorno laboral hacen que el periodo de formación de un ingeniero no acabe con la obtención de su título, sino que continúe de forma muy importante a lo largo de toda su vida profesional. La ...
