  1. 1. Design of a Dielectric Radome using a Ray-Tracing Model for Satellite Communications

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Flores Espinosa Núria; [2023]
    Nyckelord :Dielectric radome; Ray tracing; Array antenna; Lens antenna; Satellite communications; Radom dielèctric; Traçat de Rajos; Arranjament d’antenes; Antena de lent; Comunicacions per satèl·lit; Dielektrisk radome; Strålspårning; Gruppantenn; Linsantenn; Satellitkommunikation;

    Sammanfattning : In recent years, there has been a huge increase in the use of satellite communications. This has led to a need for more capacity, which can be solved by moving towards higher frequency bands in search of higher bandwidths. LÄS MER

  3. 2. Active- integrated aperture lens antenna

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Jesus Ventas Muñoz de Lucas; [2021]
    Nyckelord :;

    Sammanfattning : Luneburg lens antennas are gaining popularity in new communication systems, as increasingly higher frequencies are being used. Broadband fully- metallic implementations of Luneburg lenses, such as Rinehart- Luneburg lenses, constitute simple, cheap and efficient beamformers. LÄS MER

  4. 3. Geodesic Lens Antenna for sub-THz Imaging

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Joan Mitjans i Blasco; [2021]
    Nyckelord :;

    Sammanfattning : The Millimiter Wave (mmW) frequency band, characterized by a high atmospheric attenuation and wide available bandwidth has become of big interest for high accuracy radar imaging applications. The continuous development of the Monolithic Microwave Integrated Circuit (MMIC) technology yields to the appearance of different commercial-off-the-shelf (COTS) radar transceivers at that frequency band, where the antennas are fully integrated into the chip.

  5. 4. Mimodiegetic and Volodiegetic Levels of Diegesis, Together with Variable Frame Rates, as Tools to Define a Tentative Early Film Language

    Master-uppsats, Lunds universitet/Filmvetenskap

    Författare :Christoffer Markholm; [2017]
    Nyckelord :silent era; diegesis; frame rate; frames per second; early film; intertitles; projection; Girl Shy; The Movies; Fiddlesticks; One Week; Neighbors; Easy Street; Ask Father; The Artist; La Antena; Dr. Plonk; Languages and Literatures; Cultural Sciences; Arts and Architecture;

    Sammanfattning : This thesis focuses on the era of early film, with the aim to address an almost forgotten film language. Three aspects have been taken into account—variable frame rates, suppressed sound and hearing, and projection speeds—to analyze several examples of film to ascertain the techniques used by early filmmakers.
