  1. 1. 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)

    Author : Carl Henriksson; Jonathan Fransson; [2023]
    Keywords : ;

    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

  3. 2. Preparations for photon external beam radiotherapy treatment planning of small animals

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Joanie Diha Guei; [2022]
    Keywords : Medicine and Health Sciences;

    Abstract : Introduction:The XenX is a small animal irradiation system that acquires high-resolution cone-beam tomography (CBCT) images of small animals and treats small animals with higher precision than medical linear accelerators. MuriSlice is a software for CBCT image reconstruction. READ MORE

  4. 3. Phase control with spatial-light modulators towards application for opto-optical modulation

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Isa Hendriks; [2020]
    Keywords : phase control; spatial-light modulator; simulation; spatial phase profile; opto-optical modulation; Physics and Astronomy;

    Abstract : This project is about focusing a Gaussian laser beam that has a spatial phase profile applied by a spatial light modulator. The goal is to be able to control the shape, position and phase of the peak at the focus and to split up the peak at the focus into several peaks. READ MORE

  5. 4. Noncollinear optical parametric amplification of a supercontinuum

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Henrik Åkesson; [2019]
    Keywords : optical parametric amplification; supercontinuum generation; nonlinear optics; laser pulse compression; lasers; optics; Physics and Astronomy; Technology and Engineering;

    Abstract : During this thesis, work has been done towards realizing a short-wave infrared (SWIR) laser source based on optical parametric amplification. It is planned that this setup should be able to produce few-cycle laser pulses at 2μm with a stable carrier-envelope phase (CEP). READ MORE

  6. 5. Generation and characterization of intense attosecond XUV pulses

    University essay from Umeå universitet/Institutionen för fysik

    Author : Xiuyu Wu; [2019]
    Keywords : ;

    Abstract : Electronic dynamics in molecules and atoms takes place on the attosecond timescale. For the observation of such processes, measurement techniques with attosecond resolution are needed. READ MORE
