17. Portable HF Antennas for Concurrent Multiband Systems
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Current HF communication systems are confined to transmit in relatively narrow frequency band of a few 100 kHz at the time. The problems with limited bandwidth accumulate in HF-networks with multiple links and such networks are therefore hardly “internet capable” today. READ MORE

18. Dual-polarized geodesic lens in sub-THz
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : In the sub-THz frequency range, the geodesic lens can realize low losses and beam scanning capability with high gain and high aperture efficiency due to its fully metallic property and rotational symmetry. Therefore, in high-frequency applications, a geodesic lens is considered a more promising solution in comparison to phased arrays or other beamforming techniques. READ MORE

20. The role of bed sediments for sorption of phosphorus in remediated ditches in Sweden
University essay from SLU/Dept. of Soil and EnvironmentAbstract : Human activities have increased nutrient losses to agricultural ditches and streams, including phosphorus. Phosphorus leakage leads to a worsening of water quality in downstream ecosystems, including lakes and seas. In addition, higher phosphorus concentrations lead to eutrophication, which negatively affects aquatic systems. READ MORE
