11. Effectiveness of Iterative Algorithms for Recovering Phase in the Presence of Noise for Coherent Diffractive Imaging
University essay from Göteborgs universitet / Institutionen för fysikAbstract : Methods of coherent diffractive imaging (CDI) rely on iterative algorithms to reconstruct the complex exit-surface wave (ESW) of the object being imaged from the measured diffraction intensity only. In this thesis we investigate by simulation the artifacts on reconstruction when noise are present in the measurement. READ MORE

12. Evaluating aperture shape controller (ASC) in modulated radiation treatments
University essay fromAbstract : To decrease aperture complexity, the aperture shape controller (ASC) is a recently introduced function in Eclipse external beam planning (Varian Medical Systems, Palo Alto, USA). ASC works within the photon optimizer, minimizing distances between adjacent leaf tips of the MLC. READ MORE

14. Beam Steering Antenna Based on Continuous Transverse Stub Array and Flat Risley Prism Metasurface Lens
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Satellite communication is an integral part of society in this day and era. Due tobandwidth limitations communication frequencies have moved into higher frequencybandwidths. With the advancements in communication comes the demand for more efficientantennas due to the high attenuation of millimeter wavelength frequencies. READ MORE

15. Space-Division-Multiplexing Platform for a Delayed-Choice Experiment
University essay from Linköpings universitet/InformationskodningAbstract : This master’s thesis explores a space-division-multiplexing (SDM) platform fora delayed-choice experiment. SDM is a multiplexing technique for optical datatransmission that employs spatial modes in a multi- or few-mode fiber to increasethe transmission capacity. The spatial modes can thus be used as separate channels. READ MORE
