  2. 16. A Neural Network Technique for Retrieving Atmospheric Species from Microwave Limb Sounders

    Author : Carlos Jimenez Sanchez; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Atmospheric radiometry requires solving an inversion problem due to the indirect nature of the measurements. Traditional iterative methods for non-linear inversions are computationally intensive and faster algorithms are desirable. READ MORE

  4. 17. Submillimeter-Wave Waveguide Frontends by Silicon-on-Insulator Micromachining

    Author : Adrian Gomez-Torrent; Joachim Oberhammer; Umer Shah; Goutam Chattopadhyay; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; antenna; orthomode transducer; switch; waveguide; radiofrequency; beamforming network; submillimeter-wave; terahertz; silicon micromachining; deep reactive ion etching; silicon on insulator; Electrical Engineering; Elektro- och systemteknik;

    Abstract : This thesis presents novel radiofrequency (RF) frontend components in the submillimeter-wave (sub-mmW) range implemented by silicon micromachining, or deep reactive ion etching (DRIE). DRIE is rapidly becoming a driving technology for the fabrication of waveguide components and systems when approaching the terahertz (THz) frequency range. READ MORE
