1. Direct Nanoprototyping of Functional Materials via Focused Electron Beam
Sammanfattning : During recent years the demand for nanoscale materials with tailor-made functional properties as bulk species, is continuously and progressively rising for such fields as e.g. micro- and nano-electronics, plasmonics, spintronics, bio-technology, bio-sensing and life sciences.

2. Dual-energy imaging in stroke : feasibility of dual-layer detector cone-beam computed tomography
Sammanfattning : Background: Dual-energy computed tomography (DECT) is increasingly available and used in the standard diagnostic setting of ischemic stroke patients. For stroke patients with suspected large vessel occlusion, cone-beam computed tomography (CBCT) in the interventional suite could be an alternative to CT to shorten door to thrombectomy time. LÄS MER
3. Measurement of trace components in aqueous solutions with near and mid infrared Fourier transform spectroscopy
Sammanfattning : This thesis treats various aspects of the measurement of trace components in aqueous solutions with Fourier transform infrared spectroscopy. This technique has several applications from such diverse fields as dairy industry and biomedical optics. LÄS MER
4. Single and dual band horns for multi-beam satellite antennas - application of artificially hard surfaces
Sammanfattning : The latest trend for the multimedia satellite systems is operation at the Ka-band, 17.7-20.2 GHz downlink and 27.5-30. LÄS MER
5. Millimeter-Wave High-Gain Antenna for 5G Backhauling with Auto-beam-tracking Function
Sammanfattning : As microwave links are increasingly deployed within the millimeter-wave frequency range, E-band (70/80 GHz) links have been installed on a global scale. One major technological challenge in this high-frequency spectrum is the significant increase in path loss between receivers and transmitters. LÄS MER
