1. 26. Design of Optical Magnetic Systems for Terahertz Lensing

   University essay from Uppsala universitet/FREIA

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

   Abstract : 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. READ MORE

3. 27. Standard Compliance and Quality Assurance of Lighting Products : Creating a setup for measuring Short Term Flicker Perceptibility and Stroboscopic Visibility Measure

   University essay from KTH/Skolan för teknikvetenskap (SCI)

   Author : Julia Wollter; Alexander Willemsen; [2021]
   Keywords : ;

   Abstract : New EU regulations are currently taking effect, which means there will be stricter requirements on lighting units and more necessity for labs to perform photometric quality control. In the project a flickermeter setup was constructed at the Swedish Energy Agency's lab for performing quality assurance of luminaries by measuring the relevant metrics PST, SVM, and ITHD. READ MORE

4. 28. Development of innovative multi-physics solutions to optimize biological measure performance

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : Mathilde Aubret; [2020]
   Keywords : Camera variability; statistics; image processing; LFIA; microfluidic; modelling;

   Abstract : Paper strips are becoming widely used for blood testing and particularly with embedded immunoassays. Among the so called "Point of Care" devices, the association of LFIA tests with a reading technology able to capture the strip and analyze its composition to output the biological result is advantageous in many ways.

5. 29. Investigation of Inverse Magnetostriction inCobalt Films and Nanowires

   University essay from Uppsala universitet/Molekyl- och kondenserade materiens fysik

   Author : Ahmad Montaser Lababidi; [2020]
   Keywords : ;

   Abstract : In this thesis, a study of the inverse magnetostriction (the Villari effect) of Co nanowires and films is presented. The main objective was to investigate the stability of the Co nanowires’ magnetic properties, i.e. READ MORE

6. 30. Radiation effects on wide bandgap semiconductor devices

   University essay from KTH/Tillämpad fysik

   Author : Patric Elf; [2020]
   Keywords : applied physics;

   Abstract : Gallium nitride (GaN) based high-electron-mobility transistors (HEMTs) are used in a wide variety of areas, such as 5G, automotive, aeronautics/astronautics and sensing elds ranging from chemical, mechanical, biological to optical applications. Owing superior material properties, the GaN based HEMTs are especially useful in harsh operation environments e. READ MORE
