1. Towards a setup for narrowband terahertz generation through difference-frequency mixing of chirped ultrashort pulses
University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionenAbstract : Terahertz radiation is a useful tool for inducing lower-energy excitations in matter, where it can be used to cause structural changes through direct interaction with the crystal lattice. Sub-picosecond optical pulses can be used to generate intense broadband terahertz pulses through optical rectification in nonlinear crystals, reaching peak electric fields of several MV/m and conversion efficiencies as high as a few percent.

2. Generation of attosecond X-ray pulses in free-electron lasers using electron energy modulation and undulator tapering
University essay from Uppsala universitet/FREIAAbstract : Free-electron lasers (FELs) are among the world's most intense artificial artificial sources of coherent light and are tunable to various wavelengths, including the X-ray spectrum. X-ray FELs (XFELs) are extremely useful for diffraction experiments to study molecules, materials, and quantum systems. READ MORE

3. Phase Unwrapping MRI Flow Measurements
University essay from Uppsala universitet/Avdelningen Vi3Abstract : Magnetic resonance images (MRI) are acquired by sampling the current of induced electromotiveforce (EMF). EMF is induced due to flux of the net magnetic field from coherent nuclear spins with intrinsic magnetic dipole moments. READ MORE

4. Study, Design and Optimization of Micro Coil for NMR Applications
University essay from Linköpings universitet/Institutionen för systemteknikAbstract : Nuclear Magnetic Resonance (NMR) has emerged as a powerful tool for the iden-tification and quantification of substances. A critical component within the NMRapparatus is the radio frequency coil, which determines to some extent the sen-sitivity of the NMR device. READ MORE

5. Design and construction of a reliable wireless power transfer system for an embedded device : With emphasis on industrial applications
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : This thesis deals with wireless power transfer from an external source to embedded small devices (such as for conditioning monitoring, control etc.) located at different distances from the source. The proposed designs can be used in a variety of applications, including mobile phones, electric cars, unmanned aerial vehicles, robots, etc. READ MORE
