  1. 1. 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

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

    Author : Balwan Rana; [2021]
    Keywords : Negative-Index Material; NIM; Positive-Index Material; RHM; Backward- Wave Propagation; Step-Index Interface; Graded-Index Interface; Left-Handed Material; LHM; Right-Handed Material; RHM; Analytical Solution; Validation; Negativt-Index Material; NIM; Positivt-Index Material; PIM; Bakåtvåg-utbredning; Steg-Index Gränssnitt; Gradering-Index Gränssnitt; Vänsterhänt Material; LHM; Högerhänt Material; RHM; Analytisk Lösning; Validering;

    Abstract : The discovery of metamaterials has led to major advances in different fields of physics including optics, microwave engineering and acoustics. Specific to theoretical electromagnetism, the introduction of metamaterials have led to the development of negative-index materials (NIMs) with simultaneous negative permittivity and negative permeability with backward-wave propagation.

  4. 3. Modelling and grid integration of a 10 MW wave farm - Study of power quality with varying grid impedance angles and wave front incidence angles

    University essay from Uppsala universitet/Institutionen för elektroteknik

    Author : Md Imran Ullah; [2020]
    Keywords : Power systems; WEC; grid connection; electric modelling; flicker; voltage peaks; power factor; wave farm modelling; grid impedance angle; powerfactory;

    Abstract : Grid connection of wave energy is one of the crucial remaining areas of development towards the commercialization of this renewable energy technology. One of the major challenges with the grid connection of the wave energy technology is power variability. READ MORE

  5. 4. Development of a configurable model for temperature distribution estimation in multifamily houses with limited amount of sensors

    University essay from KTH/Tillämpad termodynamik och kylteknik

    Author : Federica Bozzi; [2019]
    Keywords : ;

    Abstract : The biggest environmental challenge of the current century is limiting the CO2 emissions in order to contrast the global warming and keep the temperature increase below 2.0K with respect to the pre-industrial age. For succeeding in this goal, significant changes are required in all sectors, including the energy one. READ MORE

  6. 5. Matched Filters for Direct-Detection LiDAR in Non-Perpendicular Measurement Scenes

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Simon Ranefjärd; [2019]
    Keywords : ;

    Abstract : The ongoing development of Advanced Driver Assistance Systems (ADAS) and autonomous vehicles pushes the requirements of accurate measurements from several on-board sensors, one of which being the Light Detection And Ranging (LiDAR). The performance of the LiDAR measurements relies partially on the reflectivity of the target, the level of background noise and the angle of incidence to the measurement scene. READ MORE
