1. Radio Emissions from Earth’s Foreshock and Bolides
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : It is well understood that Earth’s foreshock radiation is due to the bow shock deflecting the solar wind and accelerating electrons upstream into the foreshock where they produce Langmuir waves and radio emissions. Recently, the Long Wavelength Array (LWA) in the USA observed radio waves from meteors and other bolides entering the ionosphere and atmosphere. READ MORE

2. Particle in Cell Simulations of Electrostatic Waves in Saturn's Magnetosphere
University essay from KTH/Rymd- och plasmafysikAbstract : The characteristics of electrostatic waves are investigated using PIC simulations of a four component plasma: cool and hot electrons, cool ions and an electron beam. The velocities are de ned by Maxwellian distributions. The system is one dimensional and simulates a collisionless, unmagnetized plasma. READ MORE

3. Contribution from Spin-Orbit Coupling to the Langmuir Wave Dispersion Relation in Magnetized Plasmas
University essay from Institutionen för fysikAbstract : This thesis analyses the effect spin-orbit coupling has on the dispersion of Langmuir waves in magnetized plasmas, using recently developed kinetic theories of plasmas including quantummechanical and relativistic effects. Two new wave modes appearclose to the resonance = ( g/2 − 1) , where is the cyclotron frequency and g is the electron gyromagnetic ratio. READ MORE
