  1. 1. Side-channel information and electromagnetic leakage: investigation at a microstrip design level

    Uppsats för yrkesexamina på avancerad nivå, Högskolan i Halmstad/Akademin för informationsteknologi

    Författare :Niklas Dymne; Kasper Sjöström; [2023]
    Nyckelord :;

    Sammanfattning : The number of IoT devices is increasing all over the world. As with any electrical device, they emit electromagnetic emissions. These emissions pose a security threat when it comes to electromagnetic side-channel attacks. LÄS MER

  3. 2. ATLAS Inner Tracker Upgrade for HL-LHC: Silicon microstrip detector metrology

    Master-uppsats, Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

    Författare :Xiangyu Xu; [2023]
    Nyckelord :High energy physics experiment; LHC; HL-LHC; ATLAS; ITk; Metrology; Measurement; Physics and Astronomy;

    Sammanfattning : The Large Hadron Collider (LHC) will be upgraded to the High-Luminosity LHC (HL-LHC) by the end of this decade, with five times larger luminosity and 200 inelastic collisions per proton-proton bunch crossing. Thus, the ATLAS detector is challenged to survive the stronger radiation and the increased particle flux. LÄS MER

  4. 3. Design and Fabrication of a Kinetic Inductance Parameric Amplifier for multi-mode entanglement studies

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Sara Persia; [2022]
    Nyckelord :Parametric amplifier; kinetic inductance; superconducting NbTiN nanowires; Parametrisk förstärkare; kinetisk induktans; supraledanden NbTiN- nanotrådar;

    Sammanfattning : Parametric amplifiers are essential for analyzing and measuring the weak signals generated byquantum circuits at cryogenic temperatures. This project aims to realize a low noise travelingwave parametric amplifier (TWPA) by exploiting the nonlinear current dependence of thekinetic inductance of superconducting NbTiN nanowires. LÄS MER

  5. 4. 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

  7. 5. Dual-polarized fully-metallic Vivaldi antenna array in a triangular lattice

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

    Författare :Omar Orgeira Alvarez; [2022]
    Nyckelord :Base station; Mobile communications; Phased arrays; Vivaldi antenna; Stripline; Basstation; Mobilkommunikation; Phased arrays; Vivaldi-antenn; Stripline;

    Sammanfattning : New mobile communication generations need electromagnetic sensors capable of steering their high-directive beams towards the users. Conventional base stations use square lattice phased arrays to accomplish this task. These arrays are composed of a large number of radiating elements to achieve the required high directivity and scanning capabilities. LÄS MER
