  • Linear array diagnostic from near-field measurements 

    Romeu Robert, Jordi; Jofre Roca, Lluís; Soneira Ferrando, M. José; Clavera, Jordi (Institute of Electrical and Electronics Engineers (IEEE), 1989)
    Conference report
    Open Access
    The authors present an inversion procedure to obtain the current distribution on a linear array from a near-field measurement. Numerical simulations were performed for a 50-element linear array. Single elements are ...
  • Medida de parámetros de ruido de transistores HEMT a partir de medidas de ruido con fuente adapatada 

    Lázaro Guillén, Antoni; Pradell i Cara, Lluís; O'Callaghan Castellà, Juan Manuel; Pérez Pueyo, Rosanna; Soneira Ferrando, M. José (1998)
    Conference report

  • Microwave imaging with crossed linear arrays 

    Soneira Ferrando, M. José; de los Reyes, Elías; Bolomey, Jean Charles (1987-11-11)
    Article
    Open Access
    The capabilities of a microwave imaging system working in air using two crossed linear arrays are described. The analytic expressions of the focusing procedures are derived, resolution and available volume of reconstruction ...
  • Morphology-based automated baseline removal for raman spectra of artistic pigments 

    Pérez Pueyo, Rosanna; Soneira Ferrando, M. José; Ruiz Moreno, Sergio (2010-06)
    Article
    Open Access
    The interpretation of a Raman spectrum is based on the identification of its characteristic molecular bands. However, the assignment of the vibrational modes is often compromised by the presence in the spectrum of an intense ...
  • Raman laser fiber optic strategy for non-destructive pigment analysis 

    Ruiz Moreno, Sergio; Soneira Ferrando, M. José; Pérez Pueyo, Rosanna; Gabaldón Borque, Amador José; Sandalinas Linares, Maria Carmen (Office for official publications of the European communities, 2000)
    Conference report
    Restricted access - publisher's policy
    In this work, the strategy, performances and applications of a Raman spectroscopy system with both optical fibre technology and two lasers (red and green) are presented. With this system, we have investigated certain yellow ...
  • Reduction of pulse distortion in travelling wave semiconductor optical amplifiers 

    Soneira Ferrando, M. José; Ruiz Moreno, Sergio (1991)
    Conference report
    Open Access
    The possibility of reducing the gain saturation during the pulse amplification process by means of the compensation of the carrier density variations is investigated. This should be useful in many optical systems and, ...
  • Signal to noise ratio in nonlinear optical amplification process 

    Soneira Ferrando, M. José; Ruiz Moreno, Sergio (1990-01)
    Article
    Open Access
    In this communication, one looks at the influence of the saturation process over the statistical fluctuations (signal to noise ratio) of the optical power at the output of a travelling wave semiconductor optical amplifier ...
  • Statistical analysis of nonlinear optical amplifier in high saturation 

    Ruiz Moreno, Sergio; Junyent Giralt, Gabriel; Soneira Ferrando, M. José (1988-02)
