  4. 3. Cylindrical Waveguide Slot Antenna Analysis

    Författare :Johan Wettergren; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; basis function; mutual admittance; cylinder; MPIE; slot; integral equation; waveguide; antenna; mutual coupling; moment method; EFIE;

    Sammanfattning : Waveguide slot antennas with longitudinal and transverse slots are analyzed using a rigorous method. The antennas are divided into regions, which are analyzed separately and matched by a moment method procedure. At the apertures between the regions, the electric fields are expanded in trigonometric basis functions. LÄS MER

  5. 4. EC State aid rules : An analysis of the selectivity criterion

    Författare :Mona Aldestam; Nils Mattsson; Torbjörn Andersson; Piet J. Slot; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; European law; EC State aid; Taxation; Derogation; Benchmark; Norm; Selectivity criterion; Justifications; Europarätt; European law; EU-rätt; Jurisprudence; Allmän rättslära;

    Sammanfattning : The application of Art. 87(1) EC to taxes above all is connected to the application of the derogation method, which appears to be part of the selectivity criterion. This dissertation examines the application of the derogation method and the assessment of the selectivity criterion applied to taxes, primarily de lege lata, but also de lege ferenda. LÄS MER

  7. 5. Planar Quasiparticle Mixer Structures for Millimeter and Sub-Millimeter Wave Receivers

    Författare :Anders Skalare; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SIS receiver; dipole array antenna; slot substrate mode loss; millimeter wave regime; planar antennas; sub-millimeter wave regime; superconducting mixers; slot radiation; slot lines; slot wavelengths; Voltage Matching Method;

    Sammanfattning : The paper covers various aspects of integrating planar antennas with superconducting mixers in the millimeter and sub-millimeter wave regime. The construction of an 80-100 GHz tapered slot antenna and SIS mixer chip with a minimum double side band noise temperature of 240 K is described. LÄS MER
