  4. 3. Satellite signal attenuation due to atmospheric influences in northern Sweden

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Adrian Stigsson; [2024]
    Nyckelord :;

    Sammanfattning : Earth-space traversing electromagnetic waves become attenuated as they propagate through the atmosphere. The sources of attenuation are weather phenomena in the Troposphere, and scintillation and absorption in the Ionosphere. LÄS MER

  5. 4. Space-Division-Multiplexing Platform for a Delayed-Choice Experiment

    Master-uppsats, Linköpings universitet/Informationskodning

    Författare :Hilma Karlsson; [2023]
    Nyckelord :Wheeler s delayed choice; wave-particle delayed choice; Sagnac interferometer; Mach-Zehnder interferometer; complementarity relation; spatial modes; space-division-multiplexing; LP-modes; few-mode fibers; quantum communication; quantum optics;

    Sammanfattning : 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. LÄS MER
