  1. 1. Nonlinear mode coupling and parametric amplification with superconducting kinetic inductance

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Daniele Lopriore; [2022]
    Nyckelord :Quantum technology; microwave engineering; nanofabrication; parametric amplifiers; multimode entanglement; kinetic inductance; Kvantteknologi; mikrovågsteknik; nanotillverkning; parametriska förstärkare; multimodentrassling; kinetisk induktans;

    Sammanfattning : We investigate the resonant characteristics of superconducting meandering nanowires to design a nonlinear kinetic inductance traveling-wave parametric amplifier. The devices are patterned out of 15 nm thick NbTiN films. They consist of a coplanar waveguide, that shrinks into 100 nm wide meandering nanowires. LÄS MER

  3. 2. Out-of-plane Ferromagnetic Resonance (FMR) measurements on magnetic nanoparticle dispersions for biomedical sensor applications

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Fasta tillståndets fysik

    Författare :Markus Back; [2020]
    Nyckelord :Ferromagnetic; magnetic; resonance; FMR; EPR; nanoparticle; microwave; coplanar; waveguide; cavity; s-parameter; gilbert; damping; gyromagnetic; liquid; biosensor; landau; lifshits; spin; polymer; composites; engineering physics; teknisk fysik; magnetism; ferromagnetisk; vågledare; resonans; mikrovågsteknik; nanopartiklar;

    Sammanfattning : In this master work, we investigated the feasibility of a magnetic resonance measurement technique using magnetic nanoparticle dispersions in both liquid and solid form. The implementation is realised as a coplanar waveguide operating in the frequency range of 0.5 - 20 GHz and an electromagnet producing a static magnetic field of strength up to 1. LÄS MER

  4. 3. Multilateration in Direct ShortRange Communications Networks : Utilising Basic Safety Messages and Received Signal Strength Ranging

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för datavetenskap och medieteknik (DM)

    Författare :Andrew Galbraith; [2020]
    Nyckelord :DSRC; trilateration; multilateration; RSS; V2X;

    Sammanfattning : Traditional satellite positioning systems have limited resolution and have proved inaccuratein areas such as urban canyons where signals are subject to bounce phenomena or indeed may be entirely unavailable. An alternative method of positioning is that of tri/multilateration, which uses known positions and distances from beacon points to locate a receiver. LÄS MER

  5. 4. Surface guided radiotherapy for high precision treatments of brain metastases

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Elise Konradsson; [2018]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : Purpose/Background High accuracy treatment techniques such as stereotactic radiotherapy (SRT) requires precise patient positioning prior to and during treatment. The Catalyst™ is an optical surface scanning (OSS) system that has been utilized for patient positioning and real time monitoring during radiotherapy. LÄS MER

  7. 5. Flexible Time-Resolved Magneto-Optical Measurements

    Master-uppsats, Uppsala universitet/Materialfysik

    Författare :Pier Silvio TIbaldi Tibaldi; [2016]
    Nyckelord :TR-MOKE; Kerr; magnetization dynamics; magneto-optical effect; Time-resolved magneto-optical Kerr effect;

    Sammanfattning : We present a time-resolved Kerr microscope, capable of measuring the magnetization dynamics of samples grown on transparent, double-side-polished substrates.The magnetization is excited by a current pulse, using a coplanar waveguide placed beneath the samples. LÄS MER
