1. 1. Theoretical and experimental investigation of themagneto-optical eect in graphene in the THz region

   L1-uppsats, Uppsala universitet/FREIA

   Författare :Mircea-George Coman; [2022]
   Nyckelord :;

   Sammanfattning : In many optics applications we need lenses with dynamically tunable focal lengths. One design of such a lensis developed in and it relies on the magneto-optical eect. In this design, a graphene layer is placed ina magnetic eld that varies quadratically in space. LÄS MER

3. 2. Design of Optical Magnetic Systems for Terahertz Lensing

   Kandidat-uppsats, Uppsala universitet/FREIA

   Författare :Gustav Lidberg; Karl Pontén; Johan Millberg; [2021]
   Nyckelord :Terahertz; Graphene; Optics; Magnets; Optical Magnetic Lens;

   Sammanfattning : When graphene is subjected to magnetic fields, it can be used as an optical device with light in the terahertz region. The functionality of the graphene depends on which magnetic field profile is influencing it. In this project, magnet configurations producing uniform and quadratic magnetic field profiles were studied. LÄS MER
