  2. 1. Design of Functional Structures and Measurement Techniques for Electromagnetic Waves

    Author : Johan Lundgren; Teoretisk elektroteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; functional structures; frequency selective structures; polarization selectivity; metasurface; near-field measurements; antenna measurements; scattering measurement; power density; random media;

    Abstract : Electromagnetic fields exist all around us. Through evolution, nature has developed tools to interact and use these fields, where our eyes are a spectacular example. Humans have a long history of developing structures and objects of their own to alter and interact with these fields. READ MORE

  4. 2. Spatial and temporal metrology of intense attosecond pulses

    Author : Helene Coudert-Alteirac; Atomfysik; []
    Keywords : Ultrafast optics; High-order harmonic generation; Filamentation; Attosecond; Femtosecond; Extreme ultraviolet; Wavefront measurement; Optical metrology; XUV optics; interferometry; Pump-probe; Fysicumarkivet A:2018:Coudert-Alteirac;

    Abstract : Attosecond pulses are short enough to capture the electronic dynamics in atoms and molecules. The work presented in this thesis deals with the generation and optimization of attosecond extreme-ultraviolet (XUV) pulses. READ MORE

  5. 3. Investigation of Ultrafast Molecular Dynamics via Covariance Mapping : A Tool for Intense XUV Light Sources

    Author : Jan Lahl; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Covariance; Ultrafast; High-order harmonic generation; Extreme Ultraviolet; Pump probe; FLASH; Velocity map imaging; wavefront; FEL; photodissociation; Coulomb explosion; Fysicumarkivet A:2019:Lahl;

    Abstract : The study of molecular dynamics involves observations of the motion of nuclei and electrons. While nuclear motion is usually on the picosecond or femtosecond timescale, attosecond precision is necessary to directly observe the motion of electrons. READ MORE

    Abstract : Roll-to-roll manufacturing of micro components based on advanced printing, structuring and lamination of ceramic tapes is rapidly progressing. This large-scale and cost-effective manufacturing process of ceramic micro devices is however prone to hide defects within the visually opaque tape stacks. READ MORE
