    • Constructing a partially transparent computational boundary for UPPE using leaky modes 

      Juhász, Dávid; Jakobsen, Per Kristen (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-08-19)
      In this paper, we introduce a method for creating a transparent computational boundary for the simulation of unidirectional propagation of optical beams and pulses using leaky modes. The key element of the method is the introduction of an artificial-index material outside a chosen computational domain and utilization of the quasi-normal modes associated with such artificial structure. The method is ...

    • Modelling laser-matter interactions using resonant states 

      Juhász, Dávid (Master thesis; Mastergradsoppgave, 2016-05-12)
      Studying how light interacts with materials has become important for many technological applications from optical communication to developing of new materials. Therefore scientists have always tried to improve their understanding of these effects. The primary goal has always been to microscopically describe the pertinent processes. This paper provides a brief introduction into the interactions of ...

    • Nonlinear optics 

      Juhász, Dávid (Doctoral thesis; Doktorgradsavhandling, 2021-09-24)
      Nonlinear light-matter interactions have been drawing attention of physicists since the 1960's. Quantum mechanics played a significant role in their description and helped to derive important formulas showing the dependence on the intensity of the electromagnetic field. High intensity light is able to generate second and third harmonics which translates to generation of electromagnetic field with ...
