  1. 1. A theoretical framework for interpretation and prediction of magneto-optical measurements

    University essay from Uppsala universitet/Materialteori

    Author : Viktor Frilén; [2023]
    Keywords : moke; tmoke; lmoke; pmoke; magneto-optical effects; layered media; dielectric function; maxwells equations; dielectric tensor; linear respons; magnetism; light induced transistions; DFT; SO;

    Abstract : The interplay of experiments and theory is essential to deepen our understanding of magnetization dynamics. This thesis aims to serve as a bridge between these two aspects by establishing a mathematical framework that enables the computation of optical observable quantities based on theoretical models.

  3. 2. Wide-Angle Radome Design for Low-Cost Additive Manufacturing

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Martin Fajerberg; Mattias Nylander; [2022]
    Keywords : Radar; Radome; A-Sandwich; B-Sandwich; Multilayer; Polarization; Angle of Incidence; Finite Element Method; Differential Evolution Optimization; Transmission Line Theory; Honeycomb; Additive Manufacturing; Electromagnetic Theory; Technology and Engineering;

    Abstract : The radome, a portmanteau of the words radar and dome, is a protective dielectric cover to protect a radar from its surrounding environment. The surrounding environment can be rain, wind, sand, dust and whatever else that might harm the radar. READ MORE

  4. 3. Birefringence: Effects and Implications on In-Ice Radio Detection of High-Energy Neutrinos

    University essay from Uppsala universitet/Högenergifysik

    Author : Nils Heyer; [2022]
    Keywords : Birefringence; Cosmic Neutrinos; In-ice radio propagation;

    Abstract : The detection of high-energy neutrinos in the EeV range requires new detection techniques to cope with the small expected flux. The radio detection method, utilizing Askaryan emission, can be used to detect these neutrinos in polar ice. READ MORE

  5. 4. Scanning range extension by combining arrays with lenses

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

    Author : Hairu Wang; [2022]
    Keywords : Dome Antenna; Dielectric Lens; Array Antenna; Kupolantenn; Dielektrisk lins; Array antenn;

    Abstract : Array antennas, and more specifically phased array antennas, are widely used in radar detection and communication systems because of their excellent beam scanning ability and simple control. Generally speaking, the scanning function can be realized in two ways: mechanically or electronically. READ MORE

  6. 5. Dielectric properties of soda-lime silicate glass doped with TiO2

    University essay from Uppsala universitet/Fasta tillståndets fysik

    Author : Philip Sandell; [2020]
    Keywords : impedance spectroscopy; soda-lime; silicate; glass; titanium dioxide; dielectric;

    Abstract : A survey of the dielectric properties of TiO2 doped soda-lime silicate is presented. Impedance spectroscopy was used with measurements conducted in a temperature range from 298 K to 623 K and frequencies between 10-2 and 106 Hz. READ MORE
