  1. 1. Slow propagation line-based superconducting devices for quantum technology

    Detta är en avhandling från Chalmers University of Technology

    Författare :Astghik Adamyan; Chalmers tekniska högskola.; Chalmers University of Technology.; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; near field scanning microwave microscopy; electron spin resonance; parametric amplifier; superconducting transmission line; tunable microstrip resonator;

    Sammanfattning : In the field of circuit quantum electrodynamics (c-QED), the coherent interaction of two-level systems (TLSs) with photons, confined in a superconducting microwave resonator, opens up new possibilities for quantum computing experiments. This thesis contributes to the expansion of c-QED tool-box with slow propagation line-based solutions for ubiquitous techniques, such as cryogenic Near Field Scanning Microwave Microscopy (NSMM), Electron Spin Resonance (ESR) spectroscopy and Traveling Wave Parametric Amplifier (TWPA).

  3. 3. Gap Waveguide Technology- Electromagnetic Packaging and Transitions

    Detta är en avhandling från Chalmers University of Technology

    Författare :Astrid Algaba Brazález; Chalmers tekniska högskola.; Chalmers University of Technology.; [2015]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; coplanar waveguide; gap waveguide; microstrip; millimeter waves; packaging; perfect magnetic conductor; rectangular waveguide; transition;

    Sammanfattning : The scarcity of available frequency bands for new wireless communication systems, as well as the growing need for higher capacity, motivates the current interest in moving upwards in frequency. The millimeter wave frequency range is very attractive to allocate potential commercial opportunities such as short range wireless communications that allow high-speed data/video transmission, and automotive radars for both driver assistance and increased safety.
