  1. 1. Design of an Array of Patch-elements With a Band-pass Frequency Selective Surface Hybrid Radome : Analysis and characterisation of a frequency selective surface and a phased array antenna

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

    Författare :Curt-Herman Normark Frisk; [2022]
    Nyckelord :Frequency Selective Surface; Microstrip Patch Element; Circular Polarisation; Phased Array Antenna; Single Feed; Frekvensselektiv Yta; Mikrostrip Patchelement; Cirkulär Polarisering; Fasstyrd Gruppantenn; Single-matad;

    Sammanfattning : A circular polarised phased array antenna and a frequency selective hybrid radome are designed and evaluated. The antenna system is well suited as a part of a communication link between platforms with a 600 MHz bandwidth and a centre frequency of 5 GHz. LÄS MER

  3. 2. Dependency of high-order harmonics to polarisation properties of many-cycle driving fields

    Master-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Sammanfattning : Light-matter interactions can be used to probe both light and matter as they yield information on a system's state. On the ultrafast timescale, it is possible to employ these interactions to probe fast-occurring phenomena. LÄS MER

  4. 3. Survey of 3D-cinema systems

    Magister-uppsats, Institutionen för teknik och naturvetenskap; Tekniska högskolan

    Nyckelord :;

    Sammanfattning : 3D‐cinema has since the beginning of the 20 th century tried to stay put on the market. The first period was during the 1920’s, but the technique was insufficient and the people experienced discomfort. They also tried to introduce it during the 1950’s, 1970’s and 1980’s, but failed.
