  1. 1. Faraday cage för förvaring av hemelektronik och EMF-dämpning

    Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Arianne Östlund; [2023]
    Nyckelord :;

    Sammanfattning : Elektromagnetiska fält (EMF) finns överallt. De är naturligt förekommande, men teknik orsakar allt fler konstgjorda fält i olika styrkor ovanpå dessa. LÄS MER

  3. 2. Assessment of Exposure to Electromagnetic Fields from Distributed MIMO Antennas

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

    Författare :Frans Nyberg Zou; [2022]
    Nyckelord :6G; Distributed MIMO; Electromagnetic field exposure; Hybrid simulations; 6G; Distribuerad MIMO; Exponering av elektromagnetiska fält; Hybridsimueringar;

    Sammanfattning : Research on 6G telecommunication networks has been initiated. Among all potential technology components, the distributed multi-input multioutput (D-MIMO) technology is one of the promising enablers. Due to the new technology solutions, additional methodologies for assessment of electromagnetic field (EMF) exposure need to be developed. LÄS MER

  4. 3. Measuring the Pulse Duration and the Time-Dependent Polarisation State of Ultrashort Laser Pulses with the D-Scan Technique

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

    Författare :Daniel Díaz Rivas; [2022]
    Nyckelord :pulse characterisation; ultrashort; laser; femtosecond; dispersion scan; polarisation; wave plate; temporal reconstruction; electric field reconstruction; time-dependent polarisation; polarisation gate; Physics and Astronomy;

    Sammanfattning : Ultrashort laser pulses with time-dependent polarisation states have many applications, such as the generation of isolated attosecond pulses and the study of the optical chirality of molecules. In this project the polarisation gate, built from two quarter-wave plates of different orders, is thoroughly characterised in experiment and simulation. LÄS MER

  5. 4. Analysis of RISE's VIRC for Automotive EMC Immunity Testing

    Master-uppsats, Linköpings universitet/Elektroniska Kretsar och System

    Författare :Andreas Lundberg; [2021]
    Nyckelord :Electromagnetic Compatibility EMC ; Reverberation Chamber RC ; Vibrating Intrinsic Reverberation Chamber VIRC ; Cumulative Distribution Function CDF ; Rayleigh Distribution; Vector Network Analyzer VNA ; Immunity testing;

    Sammanfattning : RCs (Reverberation Chambers) has historically been used mainly for aerospace and military purposes in EMC (Electromagnetic Compatibility) testing, but the interest also seems to increase in the automotive industry (the development of an international standard for vehicles is in progress). The vehicles of the future will most likely be electrified, wirelessly connected and autonomous, i. LÄS MER

  7. 5. Investigation of Hybrid Simulation Methods for Evaluation of EMF Exposure in Close Proximity of 5G Millimeter-Wave Base Stations

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

    Författare :David Anguiano Sanjurjo; [2020]
    Nyckelord :5G; base station; EMF exposure; hybrid simulation method; millimeter wave;

    Sammanfattning : With the emergence of Fifth Generation (5G) mobile networks, the employment ofhigher frequencies in the millimeter-wave (mmWave) range and the realization of agreat number of beams in 5G radio base stations (RBS) make the electromagnetic (EM)simulation of RBS products very costly in terms of hardware and time requirements.In order to compute the electromagnetic field (EMF) exposure in close proximity of theRBS, more efficient simulation methods are required.
