  3. 2. Characterisation of terahertz integrated membrane circuits

    Författare :Johanna Hanning; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; waveguide width error; calibration; THz; membrane circuit; TRL; measurement uncertainty; single-flange 2-port; 220–325 GHz; cable flex; WR-03; VNA; S-parameter;

    Sammanfattning : In this thesis a novel measurement setup and thru-reflect-line (TRL) calibration kit for vector network analyser (VNA) measurements at 220 GHz to 325 GHz (WR-03) is presented. Measurements on passive membrane circuit devices under test (DUTs) show improvement in the S-parameters compared to a waveguide integrated membrane circuit setup in previous work, especially in reducing the ripples and increasing repeatability of the measurements.

  4. 3. Innovation in Complex Products and Systems (CoPS) : The Coordination of Technology Development within Networks and Projects

    Författare :José Adalberto Franca; Nicolette Lakemond; Gunnar Holmberg; Per-Olof Brehmer; David W. Versailles; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Complex Product and Systems; CoPS; Networks; Projects; Technology; Technology Readiness Levels; TRL;

    Sammanfattning : Complex Product and Systems (CoPS) has been considered a cornerstone of a national innovation strategy. Telecommunications network systems, aircrafts, gas turbines and weapon systems are example of CoPS, and their management are characterized distinctly different from mass-market commodity goods.
