1. Quantum Optical Description of High-order Harmonic Generation
Master-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionenSammanfattning : High-order Harmonic Generation (HHG) is a highly non-linear process in which an atom interacts with a strong laser field. The laser field lowers the atomic potential barrier allowing bound electrons to escape into the continuum through tunnel ionization, propagate, and, with some probability, recombine with the parent ion.

2. The impact of "loose " restrictions in Sweden during the COVID-19 virus , compared to the neighbouring Scandinavian countries.
Kandidat-uppsats, Lunds universitet/Matematisk statistikSammanfattning : Covid-19 is the first type of coronavirus that was characterized as a pandemic, year 2020. The prevention methods to minimize the spread of the corona virus did vary somehow between the countries. LÄS MER
3. Ray-Tracing Modeling of Grating Lobe Level Reduction by Using a Dielectric Dome Antenna
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : With the newly deployed fifth-generation telecommunications system and upcoming sixth-generation, high-gain antennas with hemispherical scanning capabilities are of high interest. Phased array antennas allow for fast scanning capabilities with electronic beam-steering. LÄS MER
4. Energy-Efficient Fixed-Coefficient FIR Filters for Millimeter-Wave Radios
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknikSammanfattning : With the introduction of millimeter-wave antenna arrays in 5G base-stations and ever-increasing data volumes, the power consumption of the signal processing in digital radio systems has increased over the last decade. This, combined with increased cost and environmental awareness, has put focus on power optimization. LÄS MER
5. Digitally Controlled Oscillator Topologies for mm-Wave Pulsed Coherent Radar
Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknikSammanfattning : The advancement of future generations of wireless communication and radar sensing warrants the need for mm-wave digitally controlled oscillators (DCOs) with high-frequency trade-offs in consideration. The purpose of this project is to investigate DCO topologies inspired from scientific literature. LÄS MER
