    This paper reports on the activities carried out by Airbus DS SAS, OMMIC SAS and ACST GmbH during the ESA study “Micro and Millimetre-Wave Detectors” A081ET03. Two European technologies for direct detection have been ...
  • Operation of quasi-optical a THz detectors in heterodyne regime 
    COJOCARI, O.; MARTYANOV, M.; MORO-MELGAR, D.; SOBORNYTSKYY, N. (IEEE, 2017)
    In recent years Schottky-diode technologies gain influence in THz systems because of their large sensitivity, wide range, high power capability and room-temperature operation. Schottky diodes rectify the RF signal directly ...
