    • A Dual Ridge Broadband Orthomode Transducer for the 7-mm Band 
      Reyes Guzmán, Nicolás Andrés; Zorzi Avendaño, Pablo Ignacio; Pizarro Lucero, José; Finger Camus, Ricardo; Mena Mena, Fausto Patricio; Bronfman Aguiló, Leonardo (SPRINGER, 2012-12)
      In this work we present a Q-band waveguide orthomode transducer (OMT) based on a dual ridge structure. It was designed to be used in astronomical projects were an excellent broad-band performance is mandatory. Of particular ...
    • First Supra-THz Heterodyne Array Receivers for Astronomy With the SOFIA Observatory 
      Risacher, Christophe; Guesten, Rolf; Stutzki, Juergen; Huebers, Heinz Wilhelm; Buechel, Denis; Graf, Urs U.; Heyminck, Stefan; Honingh, Cornelia E.; Jacobs, Karl; Klein, Bernd; Klein, Thomas; Leinz, Christian; Puetz, Patrick; Reyes Guzmán, Nicolás Andrés; Ricken, Oliver; Wunsch, Hans Joachim; Fusco, Paul; Rosner, Stefan (IEEE-Inst Electrical Electronics Engineers Inc, 2016)
      We present the upGREAT THz heterodyne arrays for far-infrared astronomy. The low-frequency array (LFA) is designed to cover the 1.9-2.5 THz range using 2 7-pixel wave-guide-based HEB mixer arrays in a dual polarization ...
    • Low-Cost Ka-Band Cloud Radar System for Distributed Measurements within the Atmospheric Boundary Layer 
      Aguirre, Roberto; Toledo, Felipe; Rodríguez, Rafael; Rondanelli Rojas, Roberto; Reyes Guzmán, Nicolás; Díaz Quezada, Marcos (MDPI, 2020)
      Radars are used to retrieve physical parameters related to clouds and fog. With these measurements, models can be developed for several application fields such as climate, agriculture, aviation, energy, and astronomy. In ...
    • Optimized corrugated tapered slot antenna for mm-Wave applications 
      Jarufe, Claudio; Rodríguez, Rafael; Tapia, Valeria; Astudillo, Pablo; Monasterio, David; Molina, Rocio; Mena Mena, Fausto Patricio; Reyes Guzmán, Nicolás Andrés; Bronfman Aguiló, Leonardo (IEEE Institute of Electrical and Electronics Engineers, 2018)
      We present a novel approach to design a high-performance tapered slot antenna (TSA) at millimeter-wave frequencies. Commonly, TSAs are designed using profiles expressed as simple functions (linear, exponential, Fermi, or ...
    • Progress Report on the Large‑Scale Polarization Explorer

A.; Sandri, M.; Sartor, S.; Schillaci, A.; Signorelli, G.; Soria, M.; Spinella, F.; Tapia, V.; Tartari, A.; Taylor, A.; Terenzi, L.; Tomasi, M.; Tommasi, E.; Tucker, C.; Vaccaro, D.; Vigano, D.M.,; Villa, F.; Virone, G.; Vittorio, N.; Volpe, A.; Watkins, B.; Zacchei, A.; Zannoni, M. (Springer, 2020)
      The large-scale polarization explorer (LSPE) is a cosmology program for the measurement of large-scale curl-like features (B-modes) in the polarization of the cosmic microwave background. Its goal is to constrain the ...
    • The upGREAT 1.9 THz multi-pixel high resolution spectrometer for the SOFIA Observatory 
      Risacher, C.; Guesten, R.; Stutzki, J.; Huebers, H.; Bell, A.; Buchbender, C.; Buechel, D.; Csengeri, T.; Graf, U.; Heyminck, S.; Higgins, R.; Honingh, C.; Jacobs, K.; Klein, B; Okada, D.; Parikka, A.; Puetz, P.; Reyes Guzmán, Nicolás Andrés; Ricken, O.; Riquelme, D.; Simon, R.; Wiesemeyer, H. (EDP Sciences, 2016)
      We present a new multi-pixel high resolution (R greater than or similar to 10(7)) spectrometer for the Stratospheric Observatory for Far-Infrared Astronomy (SOFIA). The receiver uses 2 x 7-pixel subarrays in orthogonal ...
