  1. 1. A Novel Method for Measuring Low Energy Excitations with BLS

    L3-uppsats, Uppsala universitet/Materialfysik

    Författare :Christopher Borchert; [2024]
    Nyckelord :;

    Sammanfattning : This report presents the work done on an optical setup combining Raman and BLS spectroscopy and discusses the achieved improvements of the system. After some general optimization and minor redesigning, a new alternative beam path was implemented. LÄS MER

  3. 2. Modeling the penetration of fragmented shaped charge jets

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Materialfysik

    Författare :Alexander Palfelt; [2023]
    Nyckelord :Shaped charge; Analytical penetration model; Visualization; Riktad sprängverkan; RSV; Analytisk penetrationsmodell; Visualisering;

    Sammanfattning : The penetration power of a shaped charge is an important characteristic in determining its capability. A model has previously been developed by FOI to analytically predict the penetration of a shaped charge jet striking a target at varying stand-off distances. LÄS MER

  4. 3. Magnetization dynamics in bistable systems

    Kandidat-uppsats, Uppsala universitet/Materialfysik

    Författare :Sven Backlund; [2023]
    Nyckelord :magnetism; magneto-optics; magnetization dynamics;

    Sammanfattning : The magnetization dynamics in ferromagnetic materials will depend on the specific shape of the system’s energy landscape. In most systems, the energy landscapes can be approximated as paraboloids, resulting in a typical ellipti- cal precession of the magnetization. LÄS MER

  5. 4. Domains in 1D-XY magnets

    Master-uppsats, Uppsala universitet/Materialfysik

    Författare :Damjan Dagbjartsson; [2023]
    Nyckelord :;

    Sammanfattning : .... LÄS MER

  7. 5. Fabry Pérot Nanocavity Produced via Solution Methods

    Master-uppsats, Uppsala universitet/Materialfysik; Uppsala universitet/Fysikalisk kemi

    Författare :Stylianos Kioumourtzoglou; [2023]
    Nyckelord :Plasmonics; Photocatalyis; Fabry Pérot nanocavity;

    Sammanfattning : Plasmonics have attracted significant attention from the scientific community for photoelectrode technologies since they offer tunability, large light absorption cross-sections, transparency and potential scalability. On the downside, plasmonics exhibit large absorption cross sections in a narrow window compared to the total electromagnetic spectrum, leading to relatively small efficiencies. LÄS MER
