  1. 1. Distortion and attenuation free gain-assisted Superluminal Propagtion in a Rare-Earth Doped Crystal

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

    Author : Antonius Johannes Renders; [2023]
    Keywords : Fast Light; Superluminal Propagation; Negative group velocity; Rare earth; Physics and Astronomy;

    Abstract : A light pulse that travels through a narrow spectral window, i.e. a frequency range of low absorption, within a strongly absorbing frequency range will be delayed due to strong dispersion. READ MORE

  3. 2. Birefringence: Effects and Implications on In-Ice Radio Detection of High-Energy Neutrinos

    University essay from Uppsala universitet/Högenergifysik

    Author : Nils Heyer; [2022]
    Keywords : Birefringence; Cosmic Neutrinos; In-ice radio propagation;

    Abstract : The detection of high-energy neutrinos in the EeV range requires new detection techniques to cope with the small expected flux. The radio detection method, utilizing Askaryan emission, can be used to detect these neutrinos in polar ice. READ MORE

  4. 3. PERFORMANCE OF THE PHOTODETECTOR FOR THE ACTIVE SHIELD OF THE COSI SPACE TELESCOPE

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Daniel Álvarez Franco; [2022]
    Keywords : Geant4; scintillation; BGO; CsI; simulation; COSI; telescope; photoelectric effect;

    Abstract : The COmpton Spectrometer and Imager (COSI) is a space telescope that aims to study the soft gamma regime (0.2-5 MeV), capable of performing spectroscopy, imaging and polarimetry of cosmic gamma sources. READ MORE

  5. 4. Simulation of birefringence effects for high-energy neutrino detectors

    University essay from Uppsala universitet/Högenergifysik

    Author : Nils Heyer; [2021]
    Keywords : astroparticle physics; radio detection; high-energy neutrinos; birefringence;

    Abstract : The detection of high-energy neutrinos in the E > O(PeV) range requires newdetection techniques in order to cope with the decreasing flux. The radio detectionmethod uses Askaryan emission to detect these neutrinos. READ MORE

  6. 5. REMOTE PULSE MONITORING USING MILLIMETER WAVES

    University essay from Blekinge Tekniska Högskola/Fakulteten för datavetenskaper

    Author : PRAFULL GARG; [2021]
    Keywords : Frequency-Modulated Continuous Waveform; Pulse Monitoring; E-Health; Ultra-Wide Band; Millimeter Waves;

    Abstract : With the population aging worldwide, new solutions for non-invasive health monitoring are required. Radar systems have been proposed as a promising technology for monitoring vital signs in ambient assisted living (AAL) applications. READ MORE
