  2. 16. Millimeter Wave Imaging and Phased Array Antennas for 5G and Aerospace Applications

    Author : Jakob Helander; Teoretisk elektroteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 5G; phased array; Millimeter wave antenna arrays; millimeter wave imaging; Computational Electromagnetics; Non-destructive testing NDT ; compressive sensing;

    Abstract : Phased array antennas are cornerstones in many proposed antenna solutions concerning the next generation of both airborne radar systems and wireless communication systems (5G). Additionally, millimeter wave (mm-wave) frequencies are expected to play an integral role in 5G, and are deemed well-suited for inspecting structural components used in the aerospace industry.

  4. 17. Analysis and control of magnetic forces in synchronous machines

    Author : J. J. Pérez-Loya; Urban Lundin; Anouar Belahcen; Uppsala universitet; []
    Keywords : eccentricity; electromagnetics; electromagnetic forces; excitation; magnetic fields; magnetic forces; magnetic thrust bearing; rotor drive; split rotor; starting; synchronous generators; synchronous machines; synchronous motors; unbalanced magnetic pull; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Abstract : In a synchronous machine, radial, tangential, and axial forces are generated. In this thesis, three different technologies to control them are proposed. The first one, involves the utilization of the radial forces that arise between the rotor and the stator. READ MORE

  6. 19. Optimal Performance of Advanced Radiating Structures

    Author : Casimir Ehrenborg; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Physical Bounds; MIMO Communication; Computational Electromagnetics; Antenna Theory; Optimization Methods; Q-factor;

    Abstract : Requirements on radiating structures are constantly increasing, demand for faster speed, smaller size, and higher reliability drives today's technical development. However, for electrically small structures, less than half-a-wavelength in size, performance is fundamentally limited by physical size. READ MORE
