1. Towards a Scalable and Low-Latency Softwarized Mobile Packet Core Network
Sammanfattning : The mobile packet core – a central part of the overall mobile cellular network – has a long history of evolution. Through the years, its architecture has been drastically changed to meet the demand coming from the fast growth in the number of devices as well as the introduction of new types of applications and services.

2. Bi2212 intrinsic Josephson junctions, fabrication and high frequency properties
Sammanfattning : The objective for this work was to investigate the high-frequency properties of Bi2212 intrinsic Josephson junctions (IJJ’s). Particularly, the possibility to reach the THz range with a SIS mixer is theoretically promising due to the high energy gap of Bi2212. LÄS MER
3. Magnetization Dynamics in Nano-Contact Spin Torque Oscillators : Solitonic bullets and propagating spin waves
Sammanfattning : Magnetization dynamics in nano-contact spin torque oscillators (STOs) is investigated from an experimental and theoretical point of view. The fundamentals of magnetization dynamics due to spin transfer torque are given. A custom-made high frequency (up to 46 GHz) in large magnetic fields (up to 2. LÄS MER
4. Intrinsic tunneling spectroscopic investigations of Bi2Sr2CaCu2O8+x superconductors : The fluxon lattice, resonant phenomena,flux-flow and current doping
Sammanfattning : In this thesis, the tunneling between individual atomic layers in structures of Bi2Sr2CaCu2O8+x based high-temperature superconductors are experimentally studied employing the intrinsic Josephson effect. A special attention is paid on the fabrication of small mesa structures using micro and nanofabrication techniques. LÄS MER
