  1. 1. Effect of the ICRH Antenna Position on the Coupled Power in ITER and JET

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Olle Sundberg; Vincent Forsberg; [2023]
    Keywords : ;

    Abstract : Fusion energy has fascinated scientists for decades. One reason we do not see thispromising energy source powering today's society is the fact that the process requires extremeplasma temperatures. READ MORE

  3. 2. Studies of the PMWE : Polar Mesosphere Winter Echoes

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Simon Persson; [2022]
    Keywords : Polar; Mesosphere; Winter; Echoes; ESRAD; Infrasound; PMWE; PMSE; Summer; Radar; VHF; MST; MLT; SPE; HSS; Solar; Wind; evanescent; viscosity; FCA; 42;

    Abstract : This Master thesis examines a phenomenon that occurs in the upper polar atmosphere, namely, Polar Mesospheric Winter Echoes, or PMWEs. PMWEs are radar echoes observed by Very High Frequency Mesosphere Stratosphere Troposphere (VHF MST) radar, from altitudes of 60 to 76 km at 7 to 15 UT, in the winter months from the middle of September to the beginning of May.

  4. 3. Optical forces from dielectric slot waveguides on dielectric nanoparticles

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Anton Möller; [2018]
    Keywords : ;

    Abstract : Trapping and modulating the physical whereabouts of particles are in great interest for numerous areas of applications. Traditionally, this type of control is achieved with free space optical tweezers, but they do present several problems. READ MORE

  5. 4. Understanding the Optical Principles of UV-based Antifouling

    University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Partikel- och kärnfysik

    Author : Erik Wilson; [2018]
    Keywords : Technology and Engineering;

    Abstract : In 2014 Salters et. al. introduced the concept of an UV-emitting wallpaper. By using UVC LEDs, a completely clean ship hull surface can be achieved without polluting the marine environment with biocides, normally associated with antifouling paints. READ MORE

  6. 5. Designing an Experiment to Investigate Slow Light Effects in Whispering Gallery Mode Resonators

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Karolina Dorozynska; [2015]
    Keywords : Slow light; Whispering Gallery Mode Resonator; WGMR; Atomic physics; Physics and Astronomy;

    Abstract : Slow light and Whispering Gallery Mode Resonators are two interesting and useful fields with applications in optical sensing and laser stabilisation among others. Slow light can lead to long interaction times which are useful in light-matter interactions such as sensitive non-linear optics. READ MORE
