      A real time tomographic imaging system at 100 GHz based on a retina and Modulated Scattered Technique (MST) is presented in this paper. It consists in applying a low frequency modulation to each probe of an array of antennas ...

    • Silicon micro-lens antennas for THz integrated arrays 

      Alonso del Pino, María; Llombart, Nuria; Lee, Clement; Jung, C.; Chattopadhyay, G.; Jofre Roca, Lluís; Mehdi, Imran (IEEE, 2011)
      Article
      Accés restringit per política de l'editorial
      In this paper, we describe the characterization of silicon micro-lenses fabricated by two different techniques, one using laser micromachining and the other developed using photolithographical techniques. The micro-lens ...

    • Silicon microlens antenna for multi-pixel THz heterodyne detector arrays 

      Lee, Choonsup; Chattopadhyay, Goutam; Jung, Cecile; Reck, Theodore; Cooper, Ken; Peralta, Alex; Lin, Robert; Mehdi, Imran; Alonso del Pino, María; Llombart Juan, Nuria (Institute of Electrical and Electronics Engineers (IEEE), 2013)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Silicon micromachined RF passive components such as washers, waveguide with 90 degree bends for 325-500 GHz band, and silicon-stacked blocks for W-band (75-110 GHz) GaAs power amplifiers have been designed, microfabricated, ...

    • Silicon micromachined lens antenna for THz integrated heterodyne arrays 

      Llombart Juan, Nuria; Lee, Choonsup; Alonso del Pino, María; Chattopadhyay, Goutam; Jung Kubiak, Cecile; Jofre Roca, Lluís; Mehdi, Imran (Institute of Electrical and Electronics Engineers (IEEE), 2013-09)
      Article
      Accés restringit per política de l'editorial
      In this paper, we present the design, fabrication, and measurements of a lens THz antenna that can be fabricated using conventional photolithography and deep reactive etching processes. The antenna is composed of an extended ...

    • Terahertz antennas with silicon micromachined front-end 

      Chattopadhyay, Goutam; Reck, Theodore; Jung Kubiak, Cecile; Lee, Choonsup; Siles, Jose Vicente; Chahat, Naser; Cooper, Ken; Schlecht, Erich T.; Alonso del Pino, María; Mehdi, Imran (Institute of Electrical and Electronics Engineers (IEEE), 2014)

      Increasingly, terahertz systems are being used for multi-pixel receivers for different applications from mapping the star-forming regions of galaxies to stand-off radar imaging. Since microstrip patch antennas are too lossy ...

    • Terahertz integrated antenna arrays for imaging applications 

      Alonso del Pino, María (Universitat Politècnica de Catalunya, 2013-10-25)
      Tesi
      Accés obert
      Terahertz is the portion of the spectrum that covers a frequency range between 300 GHz - 3 THz. This frequency band has proven its potential for imaging applications thanks to the good compromise between spatial resolution ...
