    • Characterization of THz radiation by collimated wavefront aperture raster scanning 

      Nuño Gómez, Daniel-Juan; Santos Blanco, M. Concepción; Gomez Diaz, J. Sebastian; Romeu Robert, Jordi; Jofre Roca, Lluís (Universidad de Málaga, 2020)
      Conference report
      Open Access
      We present measurements for characterization of the beam profile and polarization pattern of lens-coupled photoconductive antennas (PCAs) at THz frequencies using a setup with antennas at fixed positions and a movable ...

      Nuño Gómez, Daniel-Juan (Universitat Politècnica de Catalunya, 2017-09-07)
      Master thesis
      Open Access
      Covenantee:   Institut de Ciències Fotòniques (ICFO) / Universitat de Barcelona / Universitat Autònoma de Barcelona
      Extensively researched in the last years, the Microwave Photonics Technology field has a number of potential advantages including extremely wide bandwidth, very low frequency constant losses, light weight, immunity to EMI ...
    • High-frequency contactless characterization of 2D materials. Graphene, WS2 

      Arcos Gutiérrez, David; Nuño Gómez, Daniel-Juan; Ametller Congost, Lluís; Ferrer Anglada, Núria (2020-12)
      Article
      Open Access
      The electrical conductivity of two-dimensional (2D) materials without any electrical contact can be obtained using two different methods: the terahertz time domain spectroscopy (THz-TDS) method, in the range from GHz up ...
    • Optical beam steering network with multiband capability 

      Vega, Sara; Nuño Gómez, Daniel-Juan; Santos Blanco, M. Concepción (Universidad de Málaga, 2020)
      Conference report
      Open Access
      A multiwavelength (MW) optical true time delay Network (OTTDN) to feed a phased array antenna (PAA) is presented. Beam steering capabilities can be demonstrated when applying MW tuning. A Dual Electrode Mach Zehnder Modulator ...
    • Optical phase effects in reconfigurable microwave photonic filters with multiple wavelength input 

      Nuño Gómez, Daniel-Juan; Santos Blanco, M. Concepción (2021-11)
      Article
      Open Access
      Microwave photonic filters with a multiple wavelength input are analyzed. A comprehensive model assessing the impact of the phase characteristic of the optical stage is presented from which optimized design rules have been ...
    • Statistical analysis of a massive astronomical cross-matching process 

      Nuño Gómez, Daniel-Juan (Universitat Politècnica de Catalunya, 2016-04-08)
      Master thesis (pre-Bologna period)
      Open Access
      Gaia is an ESA mission to create a 3D map of our Galaxy. The main objective is to provide positional measurements for about one billion stars. Gaia will scan the same sky region about 85 times in different directions. This ...
