  1. 11. Assessment of Exposure to Electromagnetic Fields from Distributed MIMO Antennas

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

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

    Abstract : 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. READ MORE

  3. 12. Wide-Angle Radome Design for Low-Cost Additive Manufacturing

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Martin Fajerberg; Mattias Nylander; [2022]
    Keywords : Radar; Radome; A-Sandwich; B-Sandwich; Multilayer; Polarization; Angle of Incidence; Finite Element Method; Differential Evolution Optimization; Transmission Line Theory; Honeycomb; Additive Manufacturing; Electromagnetic Theory; Technology and Engineering;

    Abstract : The radome, a portmanteau of the words radar and dome, is a protective dielectric cover to protect a radar from its surrounding environment. The surrounding environment can be rain, wind, sand, dust and whatever else that might harm the radar. READ MORE

  4. 13. Development of a Level-0 Geoprocessing Platform for a Multispectral Remote Sensing Payload

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Sergio Santiago Bernabeu Peñalba; [2022]
    Keywords : Infrared imagery; VIS; NIR; LWIR; geoprocessor; geolocation; quaternions; Aistech Space; image processing; ORB; RANSAC; Sentinel; Landsat; Infraröda bilder; VIS; NIR; LWIR; geoprocessor; geolokalisering; kvarternioner; Aistech Space; bildbehandling; ORB; RANSAC; Sentinel; Landsat;

    Abstract : This thesis presented an overview of the development of a geolocating algorithm as part of a geoprocessor for raw satellite imagery. This algorithm was devised for and limited by the specifications of a state-of-the-art multispectral telescope designed by Aistech Space, hosted onboard the Guardian spacecraft, which will observe Earth through the visible, near infrared, and thermal infrared bands of the electromagnetic spectrum.

  5. 14. Tuning of the ESS Drift Tube Linac using Machine Learning

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/European Spallation Source ESS AB

    Author : Johan Lundquist; [2022]
    Keywords : Accelerator; drift tube linac; machine learning; neural network; ESS; linac; tuning; proton; longitudinal dynamics; beam physics; Physics and Astronomy;

    Abstract : The European Spallation Source, currently under construction in Lund, Sweden, will be the world's brightest neutron source. It is driven by a linear accelerator designed to accelerate a beam of protons with 62.5 mA, 2.86 ms long pulses, working at 14 Hz. READ MORE

  6. 15. Improving deep learning assistedfar-field electromagnetic sidechannelattacks on AES : Effects on attack efficiency from using additive noise and otherdata augmentation techniques

    University essay from KTH/Mekatronik

    Author : Axel Zedigh; [2022]
    Keywords : ;

    Abstract : Profiled side-channel attacks on hardware implemented cryptographic algorithms have been a well-researched topic for the past two decades and many countermeasures against these attacks have been proposed and adopted by the industry. Recently, a new form of far field EM side channel called "screaming channel attacks" have been highlighted. READ MORE
