  1. 1. Time-frequency analysis of THz-time domain spectroscopy data

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för systemteknik

    Författare :Hugo Laurell; [2018]
    Nyckelord :;

    Sammanfattning : This text investigates THz-TDS signals in the time-frequency domain. Addi- tionally this text discusses the prospects of using time-frequency analysis to alleviate distortion in THz spectrographic characterizations induced by back- reflections in the free space electro optic sampling used in the THz time-domain spectroscopy detection scheme.

    Sammanfattning : This report examines the cross sections of silver microresonators subjected to an incident light with different polarization. The microresonators had different geometries with and without broken symmetries. LÄS MER

  4. 3. A summary on Solitons in Quantum field theory

    Kandidat-uppsats, Uppsala universitet/Institutionen för teknikvetenskaper

    Författare :Hugo Laurell; [2016]
    Nyckelord :;

    Sammanfattning : This text is a brief summary on solitons in quantum field theory. An introduction to quantum field theory is made through which certain notions in the theory of solitons in quantum field theory is possible to understand. The explicit time-independent kink solutions are computed for the phi^4- and the sine-Gordon theory. LÄS MER
