  1. 1. Periodic Structures with Higher Symmetries: Analysis and Applications

    Författare :Fatemeh Ghasemifard; Martin Norgren; Oscar Quevedo-Teruel; Guido Valerio; Stefano Maci; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; periodic structures; higher symmetries; dispersion analysis; mode matching; generalized Floquet theorem; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : In this thesis, periodic structures with higher symmetries are studied. Their wave propagation characteristics are investigated and their potential applications are discussed. Higher-symmetric periodic structures are described with an additional geometrical operation beyond a translation operator.

  3. 2. Remote contact-free reconstruction of currents in two-dimensional parallel conductors

    Författare :Fatemeh Ghasemifard; Martin Norgren; Alessandro Formisano; KTH; []
    Nyckelord :Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : In this thesis, the theory of the remote contact-free reconstruction of currents in two-dimensional parallel conductors is investigated. The motivation of this study is finding a complement technique to measurement transformers which are the well-established devices to measure currents in power transmission lines. LÄS MER
